Built-in memory

The capacity of the voice recorder's own storage. The larger the built-in memory, the more material can be recorded on the recorder without the need to free up memory or use additional cards. This parameter is also important if you want to use the device also as a portable flash drive (many modern models allow this).

Frequency range

The range of sound frequencies that the recorder is capable of perceiving and recording. A person is able to hear sound on average from 16 Hz to 20 kHz, but the range of the actual human voice is much narrower — approximately 100-3500 Hz. Therefore, if you plan to use a voice recorder to record speech, these frequencies will be enough. If the purpose of the recorder is not limited to this, you should pay attention to models with a wider range — and in this case, the wider it is, the fuller and richer the recording will be.

Additional features

Connecting to a computer. The ability to connect the recorder to a computer, usually via a USB interface. Such a connection can be used to save recorded data on a computer, update the recorder's firmware, and some models allow using them as USB drives and even card readers (if there is a slot for memory cards, see above).

Smartphone control. The ability to control the device remotely from a mobile device. First of all, the function is necessary for recorders that can be installed out of reach of your hands and any movement, pressing a button on the case can adversely affect the recording. But at the moment some new hit can be written.

Lock buttons. The lock prevents the voice recorder from reacting to accidental button presses — for example, when carrying in a tight pocket or purse with a lot of things. By turning it on, you don't have to worry that accidental contact will start recording and drain the battery, erase files, etc. This feature is usually turned on and off by a slider, by pressing multiple buttons at the same time, or in some other way that eliminates the possibility of accidentally unlocking.

— MP3 player. The ability to use the recorder as an MP3 player to listen to music. Technically, almost all models with MP3 support have this capability (see “Recording Format”), however, some voice recorders have a separate “Player” pro...gramme mode that makes listening more convenient. Typically, the player function requires a headphone output (see below).

FM tuner. The tuner allows you to use the player as an FM receiver — in this range today the vast majority of music radio stations broadcast. Some models with a tuner have the function of recording from the air.

— Built-in speaker. On the voice recorder with its own speaker, you can listen to recorded materials without using additional equipment (headphones) or connecting to a computer. It can also be used to play music and FM radio (if available); however, the sound quality of such a speaker is usually not high, and its main purpose is to listen to the actual recordings.

— Headphone output. A connector that allows you to connect headphones to the recorder. Their purpose is generally similar to the built-in speaker (see above), however, the sound quality of even inexpensive headphones is often significantly higher. As a result, it is quite possible to comfortably listen to not only recordings, but also music, radio programs, etc. through headphones. (if available). In addition, headphones are well suited for noisy environments. even open models still provide some sound insulation.

smartphone control

Possibility of remote control of the sound recorder from a mobile phone. First of all, the function is necessary for those recorders that can be placed out of reach of the hands. Also, remote control will come in handy when any movement or pressing a button can adversely affect the recording.
