How does the mini digital voice recorder work? Specificity of the device. Which voice recorder is the best: tips for choosing

A device such as a mini digital voice recorder is a relatively recent invention. Its creation was preceded by the development of the very category of digital voice recorders as such, and later these devices were reduced in size, somewhat modified, which made it possible to create this new type. It is noteworthy that the mini-devices fully retain all the device options big size, and can compete with them in the quality of sound recording and other parameters.

These devices are quite specific due to the conditions in which they have to work. It is no secret that such a digital mini voice recorder is often used secretly, and can be in a pocket and under clothes. The outer layer of the material prevents the normal passage of sounds: they are muffled. That is why miniature devices are more sensitive. Also, the device can receive extraneous noise: hitting something in your pocket, in the process of rubbing with clothes. Therefore, the sound filter of the device is strengthened: it filters out extraneous noises more intensively, preventing the recording of extraneous sounds. Such a device can be easily configured to record exactly the sounds of a person's voice: nothing outsiders will be written.

The device receives sound through special holes, filters it and records it on electronic carrier... The latter is usually a flash card with a large memory capacity. Sometimes the recording is carried out as a single file - for any length of time, until the recording is stopped by the owner of the device, or the electricity charge runs out. In other cases, the device splits it into segments of 5-15 minutes - for ease of navigation and search the right material further.

This device can be connected to a computer or laptop - in order to move the recorded files, save them there or recycle. You can listen to the recording before that, because such devices allow you to play back the recorded. If necessary, unnecessary entries can be deleted without connecting to a computer. You can zero out or format your flash media to start filling it up from scratch - all of this is easy.

Thus, this high-tech device differs little from the larger samples of this technology, while usually having small advantages over the latter. Some voice recorders of this type come with a strap and look like wrist Watch.

Nowadays, the voice recorder is an integral part of some professions. It's hard to imagine a journalist without this digital device... For some, this gadget helps in study or presentations, when there is no time to assimilate information momentarily, others like to listen and analyze the moments of lectures in a more relaxed atmosphere or use a device for keeping a diary (some scientists do this to record a thought when there is no other source of information recording). The use of a digital voice recorder is justified by modern realities, where the amount of information received often exceeds the threshold for its instant assimilation.

This device will be your faithful assistant in several situations.

To understand what kind of voice recorders are, we will analyze three types of this technique: amateur, semi-professional and professional. The most famous manufacturers of high-quality digital technology in this area are several manufacturers. First place is rightfully taken by Olympus, followed by Sony, Ritmix and Phillips. They differ in price, characteristics and capabilities. You can learn more about this from the 2017 ranking, where the best voice recorder will be selected.

The tenth place is occupied by a device from a well-known manufacturer in Russia. At a price from 1790 to 2907 rubles. it can be attributed to models in the starting category... The gadget is perfect for recording indoors, where there is no extraneous noise. For other tasks, you should pay attention to more specialized equipment. The model's characteristics are: a single recording channel, 2 GB of internal memory and a small LCD display, perfectly readable in the dark and in the light. There is a small speaker, support for WMA and MP3 formats is announced. The recording is converted only to MP3, but there is voice authorization and the ability to choose the quality (2 options). The interface for connecting to a PC is standard, USB2.0. The display has an indication of the charge level, as well as a display of the remaining space for recording. The claimed battery life is on average 14 hours, which is a pretty good result.

The battery is built-in, lithium-polymer, does not have a "memory effect", so there is no need to pump the battery by discharging it to zero.

The case is not easily soiled, it fits well in the hand. The set includes a cord for connecting to a PC and charging, as well as headphones.

Positive feedback on the DVT1200 and high popularity among users talk about high consumer characteristics, however, it is worth dwelling on them in more detail: the recording format is single-channel (mono), the type of memory is combined (built-in and external). The volume of its memory recorder is 4 GB, expandable with an SD memory card. There is a built-in display, a speaker, and the device can be used as a flash drive.

Unlike the previous model, the recording format here is ADPCM, which indicates a more serious hardware filling.

The device can be used in large rooms, but it still does not do a very good job of suppressing noise. A good frequency range (from 750 to 18000 Hz) allows you to work with the voice, capturing its timbre and shades. The microphone of the device has a change in sensitivity. The recording quality can be adjusted (3 options). On a single charge, the gadget can last up to 23 hours in high quality mode and up to 270 hours when recording in the lowest quality. USB 2.0 data transfer protocol, headphone jack and key lock. The package contains a cable for connecting to a PC.

Before us is a good professional voice recorder from a highly specialized manufacturer. Despite some functional limitations that may surprise inexperienced users, this device has absolutely everything to conduct a professional interview. The gadget is also suitable for recording a lecture or reading a book in audio format. The price is rather big, but, here it is worth repeating, this is professional equipment with a complex filling, therefore 12590r. should not scare off everyone who wants to join the high quality sound recording.

The clear advantage of this device is its own high-grade lithium-polymer accumulator battery, as well as a body made of high-grade metal.

But the benefits don't end there. Imagine, you need the device right now, in the field, and there is nowhere to charge. In this case, the recorder provides solar battery. Know-how that is not found even in top-end devices! As many as 8 recording modes, PC connection, recording frequency range from 100 to 10000 Hz.

The review of voice recorders would be incomplete without mentioning the domestic manufacturer. A holiday for fans of domestic high-precision technology - the device turned out to be surprisingly harmonious. Appearance may raise questions, but this is already a matter of taste. The case is austere, but strong, resistant to scratches and falls. Let's just say, of all the recorders discussed above, it is Soroka who is able to survive a serious fall on the tiled floor, the rest have much less chances due to the fragility of the structure. Here, the weight of the device plays into the hands - only 15 grams. And this is with the battery installed!

According to some criteria, this device can be considered not as professional, but already as spy technique... Ideal for hidden recording. The cost of the Magpie is 19,290 rubles. The amount is not small, but given the size, it can be forgiven for this shortcoming. The main features are as follows: two active microphones for recording, only external memory (microSD), the range of recorded frequencies is from 50 to 7000 Hz, but given the hardware, there is no doubt about the quality, it will be up to par. There are two microphone inputs, its own battery and password protection. The body is made of thickened plastic, resistant to various influences.

We looked at ten different models voice recorders. Each of them can be attributed to one or another price category. In addition, all models differ in characteristics. In any case, the choice available on the market allows the buyer to choose a product based on their preferences and budget.

Before heading to the store for a new digital voice recorder, remember that we already have this thing. I say exactly - in a cell phone. And in any, even the most inexpensive. Voice recording is one of the basic auxiliary functions cell phonelike a clock or calendar.

Why, then, do we need another electronic "toy"? The fact is that using a cell phone as a voice recorder is not quite convenient. Here are just the most noticeable flaws.

The microphone of a cell phone has a circular directivity and lack of sensitivity to record sound from a distant source. In other words, you won't be able to record a lecture with your phone. The voice recorder has a more sensitive microphone. And in many models of the middle and upper price level, the sensitivity and directivity of the microphone can be adjusted by selecting discrete values \u200b\u200bwith a switch. In one position of the switch we record our own voice - the sound source is near the microphone, in the other position we record the voice of the lecturer - the sound source is ten meters from the microphone.

Further. Voice recording time for cell phones is usually limited. For simple models - one minute. This means that one voice memo cannot be longer than a minute. The limitation seems to be serious, although in fact, if you do not record lectures or long interviews, you can ignore it. Memories are rarely longer than 30 seconds. Try it yourself - you can fit a page of typed text into a one-minute audio clip at the most calm dictation pace. The need for such volumes is extremely rare.

A cell phone, especially the simplest one, may not have the means for rewriting audio files of dictaphone records on a computer (except through the audio input of a computer, which is fraught with severe distortions due to double conversion of sound - from “digital to analog” and from “analog to digital”).

The question may arise: why do this? Didn't we say that the function of synchronizing the recorder with a computer in practice often turns out to be unclaimed? Yes it is. If we are not going to keep an electronic archive of dictaphone records, synchronization is not needed. But the voice recorder buttons are designed in such a way that they are convenient to use when decrypting recordings. Find desired file, start playback, press the pause button. We write down the text in a notebook. We rewind the recording a bit, listen "with overlapping", again write down what we heard in a notebook ... Try to do the same with the phone. You have to rewrite the dictaphone recording file on your computer and decrypt it using a good software player.

The last notable drawback of a cell phone as a voice recorder is the inferior quality of sound digitization than that of digital voice recorders. There is no choice of compression level. There is no clear, convenient system for cataloging records.

It turns out that the cell phone is unsuitable for recording voice notes? Nothing like this! This is the most convenient tool, which, as is the case with the camera built into the phone, is always at hand. You can forget a digital voice recorder or the same camera (if we have already touched on this topic) at home - you will not forget your phone, because without it, it’s like no hands.

A telephone as a voice recorder is sometimes more convenient than its full-fledged brother. How do you use a voice recorder? They bring the device closer to their face and speak into the microphone by pressing a button. Note: it is brought up like a microphone. And a cell phone is like a telephone. That is, to the ear. Will it be possible to make a dictaphone recording imperceptibly, without attracting the attention of others? Only if the note is recorded on the phone. Situations when you shouldn't show your dictaphone to anyone are easy to imagine yourself. And on the phone, people talk every minute and everywhere. Cell phones are not suspicious.

And yet we decided to buy a digital voice recorder. They brought the box home. They opened it. Enjoyed the wonderful view of the new "toy". What's next?

You know, what happens to moleskines often happens with dictaphones. I bought a magnificent notebook from an elite office supply store. And it is a pity to cover its pages with hasty letters. And not the cheapest purchase is lying in a drawer of a writing desk. And we still write memorabilia on various pieces of paper, or, at best, on sticky pieces of paper.

For a voice recorder to be of real use, it must be used. Constantly. Everyday. This wonderful smart car takes some getting used to. Develop the habit of turning on the recorder as soon as you need to remember something or write down on paper.

Here is a typical scenario for using a voice recorder in everyday life. I use it as an example - in an effort to demonstrate how convenient these chic electronic things are. To live comfortably not only for me, but also for you.

Morning. The dictaphone lies on the bedside table and at the right time, programmed by us, says in the voice of a loved one: “It's time to wake up, dear. The trumpet is calling. You can record music - without any connections to the music center. One has only to bring the recorder to the sound source and press the record button. If you choose the lowest compression level (best recording quality), you will be surprised how well the recorder can record the sounds of music. Although it is better to use a real player for listening to music (but it usually does not have a built-in speaker, and therefore it is inconvenient to use it as an alarm clock - you won’t sleep with headphones on).

The voice recorder, if left on the kitchen table, works like an audio note. When you return home, and your spouse is absent for some mysterious reason, you turn on the dictaphone left by her and hear the reassuring: "Lunch is on the floor, I am at my mother's." Well, isn't it lovely?

We go down the street. We hurry to work. And suddenly a school friend met. Have not seen each other for a thousand years! And time is running out. Come on, buddy, my phone, I'll call you back. There was a piece of paper somewhere. And a pen. Oh, you, my God ... Turn on the recorder. Dictate the phone number. In the evening, copy it into a notebook or cell phone memory. And - talk to your friend calmly.

We're at work. The chief yells at the hushed staff.

- Task completed? How is it not fulfilled? What is it ?!

- And you gave another task, chief.

- Can not be!

And - we slip the dictaphone to the authorities ... No, the idea is not very good. This can ruin your relationship with management.

Okay, another story. We sit behind the wheel of a car and go on business. And suddenly - a traffic cop (or whatever they call them there today). And I didn't break anything. He claims to have violated. Take the recorder out of your pocket. Write down the words of this campaigner. He has no right to refuse. But his aplomb will fly off instantly. And a dictaphone recording can help you if things take a bad turn ...

Need more examples? I think enough. A dictaphone is a very useful thing. Just start working with it, and you will understand it yourself.

Based on the purpose of the recorder, the most important characteristics of the recorder are operating time and sensitivity.
Manufacturers love to make loud promises like "300 hours of work", "sensitivity up to 100 meters", but should they be trusted?
What characteristics should you pay attention to when choosing a voice recorder, and which are just a publicity stunt, I will tell you about this in this article.
So, How to choose a voice recorder ...

Digital or analog?

Analog - a dictaphone in which recording is made to a cassette. Such today can only be seen in the movies.
All other voice recorders are digital. They record on a memory card (external or built-in), and they differ only in the recording format.

* - there are also professional voice recorders, where digital signal recorded on a digital cassette, but for domestic purposes they are too expensive, they are not sold in kiosks, and are not considered in this article.

Voice recorder recording format

Sound can be recorded in compressed or uncompressed form. Typically, voice recorders use WMA and MP3 formats.
Recording in mp3 format is good because the recorded material can be rewritten immediately and listened to without processing on any mp3-player, it takes up much less disk space.
The only advantage of the wma format is that although they take up much more disk space, due to the lack of compression, it transmits everything that was recorded from the microphone without loss of quality.

However, if the dictaphone provides recording in mp3 with "high bitrate" (what is it - read on), you will not hear the difference in sound.

Pay attention to the phrase "everything that you recorded from the microphone" - no matter how good the format is, the quality of the recording also depends on the microphone.

Recording time is one of the most important characteristics

Manufacturers often attract customers with loud slogans like "120 hours of recording", or "300 hours of continuous work." You should always wonder what is behind such promises.
The recording time is determined by both the capacity of the memory card and the recording format. Of course, you know that the higher the compression ratio, the lower the sound quality. For mp3 files, the compression ratio is determined by such a parameter as "bitrate" (there is also a parameter "sampling rate" - but I will not bore you with technical details).
It is believed that CD quality is provided at a bitrate of 256 kbps (there is still 320 - but this is already a delight). A bitrate of 128 kbps provides the standard sound quality that cheap computer speakers provide.
When recording a voice, consider the purpose for which you are recording. If you just write something to yourself as a keepsake, holding the recorder right in front of your face, the lowest quality will suit you.
It will be like a voice in a police radio “Fifth, fifth, I'm going to the second point. How do you understand? Welcome. " - i.e. the words can be distinguished, but guessing who pronounced them is already difficult.
But if you are recording a stormy dispute with a large number of participants, it is important for you to distinguish not only the words on the recording, but also to recognize the voice of the one who pronounced them, and even to hear the muffled comment of one of the participants. In this case, you will need high quality recording (i.e. high bit rate or low compression).

Manufacturers, in an effort to increase the time indicated in advertisements, often deliberately introduce an ultra-low bit rate mode. And, of course, no one will call the modes like this: 128 kbps - "normal", 64 - "bad", 32 - "very bad", 8 - "terrible". Rather, they will call 8 kbit / s - "good", 32 - "improved", 64 - "super quality", 128 - "super extra pro". And on the package they will write "48 hours in good recording mode."

Therefore, when comparing voice recorders, focus on one recording mode, for example, 128 kbps - this mode provides good quality, for example, for recording lectures in a large audience.

Battery life or power consumption

A parameter that is rarely where you can find out, but it depends on it real time voice recorder operation.
No batteries last forever, and how long they last will ultimately determine whether you can record all the lectures or not.

The operating time depends on the capacity of the batteries (accumulators), so it is simply impossible to indicate it, but knowing the power consumption, you can calculate the real operating time.

For example, the power consumption of the voice recorder during recording is 600 mW / h (0.6 W / h).
You have batteries with a capacity of 1200 mAh (1 A / h).
Then: Total power for two batteries \u003d 1.2 A / h * 1.5 V * 2 \u003d 3.6 W.
Working time \u003d 3.6 W / 0.6 W / h \u003d 6 hours.

Capacity (in megabytes and gigabytes)

The recording time depends on the capacity: the more, the better.
But dictaphones can be compared only if they have the same recording format. If you choose models that record, for example, an mp3 bitrate of 64 kbps, it is clear that a 2 gigabyte recorder will record more time than 1 gigabyte.
But if a 2-gigabyte writes a bitrate of 256 kbps, and a 1-gigabyte writes a bit rate of 64 kbps, then a 1-gigabyte one will fit more recording time.

Removable memory card

With the falling prices for flash-media, and the increase in write speed, manufacturers begin to provide the opportunity to use external media.
If during the recording process you are separated from your computer for a long time, removable memory cards can be useful - they expand your possibilities.
(For example, I take a dictaphone on trips, and being torn away for 1-2 weeks from the computer, I like to write down my impressions.)

Voice recorder sensitivity

The sensitivity of the recorder determines the distance from which it can record a voice. It's one thing when you write down your thoughts or interview while holding the recorder in front of the speaker's face, it is another thing when you record a teacher in a lecture or threats from a drunken neighbor being at a considerable distance from them.

Here manufacturers will try to confuse you in technical characteristics, frightening with different "+74 dB", "-58 dBV" for the microphone. In fact, all these data make sense only if you buy an external microphone for an amplifying system, the parameters of which you know: from them you can calculate what voltage you need to apply and how much to amplify the signal in order to get an acceptable sound.
For voice recorders, these data are no more useful than the values \u200b\u200bof the supply voltage on the microcircuit.

The only significant parameter can be the sensitivity, indicated in meters, by which you can find out at what maximum distance the speaker can be, so that his voice can be recorded.

It's actually better to try making a trial recording and listen to how good the recording is.

This function automatically stops recording when silence occurs, and turns it on when the conversation starts.
It can be useful, for example, when the teacher is giving a lecture, and then, for example, for some time writes something on the blackboard - the recorder will not record the sounds of moving chalk, but will only record the teacher.

Please note that activation does not turn on instantly, and often the beginning of the first words are "swallowed".
If you are going to use voice activation, make sure that the recorder has an activation threshold adjustment - i.e. so that he could be taught which volume should be considered as noise and which as a useful voice.

Allows you to set the threshold that will be considered silence.
For example, if you are sitting at a lecture in an audience where the windows are open, a small noise comes from the street, but it is much quieter than the lecturer's voice. Automatically, street noise is not silence and needs to be recorded. From your point of view, street noise when the teacher is silent is not worth writing.
You can set the noise level below which you want to stop recording.

Modes "street", "interview", noise reduction

Any dictaphone, when recording, captures all surrounding sounds. And if in a quiet room all voice recorders work perfectly, then, for example, on a noisy street, too much is recorded. extraneous noisedrowning out the voice.
For this, manufacturers add special modes such as "street", "interview", etc. In these modes, the corresponding filters are automatically turned on or off. For example, in the "street" mode, everything that does not look like a voice is cut off. At the same time, the voice itself becomes poorer, but extraneous noise also disappears.
(Note: Each manufacturer names these modes differently.)

Automatic gane control (AGC)

This function automatically adjusts the microphone gain level based on the input signal. If the people being recorded speak loudly, she slightly muffles the sound; if they start speaking softly, she increases the volume.
This can be useful if you have multiple voice sources speaking in turn and at different volumes (or at different distances from the microphone).

External microphone

An external microphone is useful when the recording direction is known exactly, or when the recorder itself cannot be pointed or brought to the source of the voice.
The built-in microphone records voices from all directions, and, for example, when you are doing an interview, it is important for you to catch only one voice from the surrounding noise. You can use an external microphone and point it towards the speaker, eliminating extraneous noise from the recording.
Similarly, when you only need to record yourself, you can put the voice recorder in your pocket, and attach only a lapel with a microphone, and exclude when recording external noise.

Frequency Response Range

According to the recorded frequency range, voice recorders are divided into voice recorders for voice recording and for music recording.
The difference is this: from your physics course, you will, of course, remember that our ear perceives sounds with a frequency of 20 to 20,000 hertz. And human speech fits into the range from 300 to 3,000 hertz, so a larger range is simply not needed to record speech.
Therefore, ordinary household dictaphones record exactly the frequency range from 300 to 3,000 hertz (this can significantly reduce the volume of recorded files). But there are also special dictaphones for recording music, where the frequency range is expanded to acceptable values \u200b\u200b(though usually external microphones are used for this).

Stereo recording capability

Usually, when recording a voice, stereo sound is not needed - the gloss comes from one source. But sometimes this function can be useful, for example, when recording disputes.
Remember that stereo recording requires more disk space.
And often the built-in microphone only provides monaural recording, while stereo mode requires an external stereo microphone.

Built-in tuner

The tuner built into the recorder is one of the "non-core" add-ons. Allows you to listen to the radio. Radio recording is often possible.

Accelerated listening mode

Needed to find the right place on the record. This is a fast rewind, during which you can listen to what has been recorded in fast mode.
Some voice recorders even have an accelerated mode without changing the timbre of the voice.

Adapter for recording telephone conversations

A device that connects to a landline telephone: the telephone cable is plugged into it, and then the cable coming out of the adapter is connected to the telephone.

Internal folder organization

Voice recorders often allow recordings in different internal folders.
This can be useful when you are recording different types of notes. For example, at a lecture, you write down a professor, and then in the corridor you write down your thoughts about what you heard. To make it convenient to search for materials later, you can initially record, for example, the lecturer in the "A" folder, and yourself - in the "B" folder.

Limiting the number of records

Despite the fact that the recording time can be very long, in any recorder (as in any file system) there is a limit on the number of recordings (number of files).
If you like to take short notes, this limitation can be significant for you.

Ease of management

This is probably the deciding factor when choosing a voice recorder.
The voice recorder can contain as many useful functions, but if access is difficult for them, if you cannot quickly get information in which mode the recorder is currently working - all the "bells and whistles" for practical use will be useless.

Batteries

Typically, voice recorders can use standard AA or AAA batteries (to reduce size).
But sometimes there are models using non-standard batteries, which are extremely inconvenient to use.

Equipment

The minimum kit sufficient for operation is the recorder itself (batteries are purchased separately).
A built-in microphone is often included (it is difficult to buy it separately).
Usually, the kit also includes a USB cable - it is especially important to check this if the recorder has a non-standard connector.
Sometimes the manufacturer also provides headphones.

Of course, if the recorder has a non-standard battery, it should also be included in the kit.

Connection interface

Modern voice recorders are connected to a computer via a USB port as external drivewhose contents represent folders with mp3 files.
But there are also dictaphones, which come with a special proprietary program that allows you to extract the content.

It is more convenient, of course, to see the content as a collection of files.

What you need to buy additionally

For frequent use of the recorder, you need 2 sets of rechargeable batteries. Even if the recorder can work for 24 hours, the charging time will come, but it does not happen instantly. And then, psychologically, it is always useful to have a replacement kit so that you can think about the recording, and not about whether you have enough batteries.
Batteries differ not only in type (size), but also in capacity, measured in milliampere-hours, and indicated on them: the higher the number, the greater the capacity (usually sold from 1200 to 2700 mAh). The required capacity is determined only by the parameters of the recorder.
Together with the batteries and charger... They are all standard (the only difference, to put it simply, is that there are light and cheap ones that charge for a long time, and there are expensive and heavy ones for which charging takes place quickly; from practice, cheap charging is enough to work).

If there were no headphones in the kit, buy headphones, they will come in handy for listening to what was recorded in any crowded place.

It would seem, why do you need a dictaphone at all, if you don't work as a journalist, interviewing people day and night? But it is needed, because life in Russia today is developing in such a way that without a dictaphone, wherever you are, you are in a deliberately losing position. Why are we so sure of this? Well, at least because we ourselves use the dictaphone almost every day, and it really helps to cope with a lot of problems.

Use the voice recorder as a diary

If you are lazy to keep a diary, but always wanted to do it, then use instead of boring notebook or document word dictaphone recording. This format is convenient for a number of reasons. Firstly, you don't need to look for a pen and a book to write down a "brilliant" idea. You just take out a dictaphone, write it down, and enjoy the result. Recording is always prompt. Secondly, audio recordings are very convenient to store, and they weigh a little. These are not at all piles of papers that will be scattered on the table in the event that you want to keep a diary in the old way.

Guarantor of agreements

We recommend keeping a record of any business conversation that may involve money. Yes, perhaps your partners or colleagues will not like that you write them down (it is better to warn them about this, by the way), but you will even less like the fact that they will not fulfill their obligations, and instead of proof of their non-fulfillment, you will have empty words, which remained in memory, and not on a piece of paper or writing. Perhaps the record does not always have legal force, but it may well be the guarantor of agreements of one level or another. And, again, such a guarantor is quite convenient for itself.

Your help for developing public speaking skills

With the help of a voice recorder, you can even develop your skills, for example, oratory. Everything is simple here. Your speech can sound great in your head because you perceive your voice with distortion, which is quite natural.

Other people hear your voice differently, and it can be very different from what you hear differently. Therefore, it is important to train the skill of a public monologue with a voice recorder. With its help, you can adequately perceive your mistakes, speech "bugs", slowed down pace and so on, so on, so on. The dictaphone recording clearly demonstrates where you went wrong. This means that you can fix anything you want.

Life hack for your holey memory

Let's add another application of the recorder to our list: you can record lectures, important conversations, lists of products that need to be purchased for the holidays on it. In other words, the voice recorder in this case will become part of your memory, freeing the brain from unnecessary stress. In general, the fast pace of life that we see in any city is conducive to this format of "memorization". We use it - it helps perfectly. When there is information overload in your head, it is very difficult to memorize everyday things that are necessary simply for normal life functioning, and the recorder saves. Try it yourself.

"Witness" in court


Again, the record can be falsified, so it may not be a serious argument in court, but, on the other hand, it can help your lawyer or investigator understand the case, and this will greatly facilitate the legal process. Dictaphone recordings are often used by journalists as an argument in favor of a particular material. By doing this, they periodically save people who are under strong pressure from various structures. Actually, if you read the news, you probably saw the "leaked" records, which were made only in order to find the truth or to protect yourself. Therefore, yes, a voice recorder is not a whim, but a necessity that can save you. Tested by hundreds of people.

In general, we watched different voice recorders for a long time. The range of prices for them is large. Some may cost thirty, others a couple thousand. Actually, the choice must be guided by common sense. The recording quality doesn't have to be studio quality, but it doesn't have to be lousy either. The price should not shock, and reliability should be guaranteed by a reputable manufacturer. If there is a guarantee, then this is only a plus. In general, there are three models of voice recorders that we have selected for you. All brands are Ritmix, and in our opinion, it is they who have best ratio prices and functionality.

Ritmix RR-610

It is a convenient and compact voice recorder that combines the functions of radio and music player... Very easy to operate, and any recording goes to internal memory or microSD in WAV format, which is universal solutionthat does not require conversion. There is also a voice activated VOR recording function. If you turn it on, the device will start recording automatically. But the main advantage of this model is the presence of a USB connector, which will save you from the hassle of wires.

Ritmix RR-810

It is a digital voice recorder with excellent recording quality. It is equipped high quality speaker, several recording modes, removable disk support function (that is, you do not need to install additional. software for work with a PC). The record itself easily suppresses external noise - the output recording is extremely clean. Separately, we highlight the excellent write protection from accidental deletion... And on it, like on the previous one, you can listen to music and radio, there is even a hearing aid function. Plus, thanks to the replaceable batteries, you don't have to worry about the battery life cycle - you bought new ones and threw out the old ones.


Ritmix RR-989

This is a versatile voice recorder with two built-in high-sensitivity microphones at an angle of 90 degrees for natural stereo sound recording. As for the functionality, the model has incorporated all the functions of the two previous voice recorders, so we will not repeat the description, but simply note that in terms of price / quality ratio, it is an ideal choice.
