Choosing voice recorder

One of the most positive aspects of the present time is the possibility of a person through the use of its achievements to improve quality of life. Just a decade ago to have a computer, washing machine and microwave oven was considered a luxury, but today we perceive these items as necessary household appliances. Many convenient and essential equipment and devices to help modern man to keep pace with the rapidly changing world. Among these can be attributed recorders.
Today, of the bulky and noisy cluster of devices they have turned into a beautiful and compact product. Modern recorders have excellent sound characteristics and the presence of a set of comfortable additions that would make the writing process easier and more convenient. Therefore, these elegant and sometimes irreplaceable device on the right are increasingly gaining its market position. But in a wide range of recorders, the proposed shops today, the consumer is difficult to immediately determine the choice. Let us try a little bit to understand the situation on the market and accents in this matter.
You get the recorder to be used for its intended purpose, to record audio files, and so, naturally, that the main indicators of the recorder, which should affect your choice should be the characteristics that make good quality is ensured when you play back recorded sound fragments . These indicators include ...

Record format
This parameter is most models is characterized by the possibility to record acoustic signals in a compressed format (MP3) and uncompressed (in WMA format). The lack of compression, of course, provides a higher quality recording, but the data take up more space on the disk. Select the type of codec, audio compression is focused on the basic characteristics of the speech signal, and if the recorder has a good patency rate of the recorded bits of information (from 128 kbit / s and above), the sound quality is unlikely to suffer from compression.

Maximum recording time

The index, which depends on the capacity of the memory card, built-in voice recorder, as well as used in the recording format. It is not necessary to treat confidentially characteristics, which you can specify a vendor interested in purchasing your face, take a look at the recording time with a good bitrate of 128 kbit / s, it will be a measure of how a particular recorder is suitable for you on this characteristic. In the description of the technical data of these modes are often referred to as the SP and LP, then your option - this time recording when using SP. A memory capacity affects the cost of the device, determine for yourself because a valid value for money and recorder. To ensure quality recording within 4-5 hours of missing cards at 128 MB, which is using the LP mode recording time will provide up to 60 hours.

The range of accepted and Frequency
This characteristic is in good voice recorders models ranges from 100 to 6000-10000 Hz, which makes it possible to make not only high-quality voice recording, and recording music passages. The specified range in size up to 3000 Hz will not be able to capture more high notes in the voices of people talking, giving dips in the sound. If a passport is set to the recorder from 400 to 4000 Hz, it can provide a sufficient level of quality of written pieces.

Autonomy, or battery life at no extra charge
The parameter that you can not find the data sheet. But there is shown in the recorder's power consumption mW / h or w / h, as well as the capacity of the battery in mA / h or A / h Multiplying the rate of capacity and voltage that the battery is typically 1.5 V, and for different types of batteries from 1.2 to 3.7, you can get a value that indicates the battery power supply. Get the number of hours you can, if you divide the value obtained in the power consumption of the recorder.
Sensitivity of the recorder
This parameter indicating at what distance from the object can be carried out writing for the sound of normal quality. You can purchase a compact recorder for recording the distance for a possible record up to 12 meters, but sometimes it's better to try once, than to believe in a written technical description and just do a trial version of the recording at a certain distance, to ensure the accuracy of this data.



The presence of APV
This function is only required if the dialogue will be written with the participation of several people. Automatic gain control allows you to make the sound rather flat and the best to play through the ability to mute a loud and too quiet to strengthen the voice signals. Of course, the sound quality is also dependent on the presence of internal or external microphone, if you need records sent from a particular source, as well as the work of special filters that allow you to change the recording mode depending on the situation (outdoors, indoors), suppressing noise, excellent from voice signals.
For some, may be important to have a replacement card, which allows you to increase the recording time, as well as the possibility of using activation of the recorder with your voice that will help avoid additional loss of time by turning off the recording device in the absence of a voice signal. Maybe you will like the model with the ability to set the timer recording when the recorder starts to work at a certain fixed time. For better orientation in the general mass of sound fragments useful indexing function, where for a quick search, you can leave markers at certain points in the record.
Specialists site www.dictofonam.net, which by nature of their work should be aware of virtually all voice recorders, it is recommended that if security is important to you, you can pay attention to the possibility of setting the password to access the data entry functions, or concealment of phonograms. Very convenient are those models recorders, in a design which provides a USB-input for easy and fast data transfer to PC. And the possibility of buying the recorder with such additions as a tuner that allows you to listen to some radio, or an adapter for recording from your phone depends on your wishes and financial possibilities.
To determine the priority of quality characteristics that are especially worth paying attention, you must define the goals of the recorder. And from what you give it features a major role, and will depend on your final choice of the model.
