Digital voice recorders are useful compact devices, which are used for recording voice data. They have an improved sound quality due to the advanced sound technology. Let us take a look at this device and its information on how to use it.
The phonograph was the first instrument which was used for sound recording. It was used mainly for studying languages. The voice of the native speakers of a language was recorded and other non-native people learned the language and the pronunciation using the recorded voice.
After some years, cassette recorder was used to record voices, though with low sound quality. Later, after the advent of digital voice recorders, voices could be recorded with a better sound quality, file sharing and with more convenience in usage.
Well, this device functions almost in the same way as a tape recorder, except that, it doesn't have a tape. As the recording and listening process is easy and quick, it is widely used by students, interviewers, academicians, journalists, etc., to record their voices and re-record them if they choose to.
Digital voice files are incorporated to record the voice data. The voice data is stored in the form of discrete numbers, and the value depends on the air pressure involved during the voice modulations. But the input is a continuous stream of analog data.
The analog signal is converted into digital signal by Analog-to Digital Converter (ADC). The output of the ADC is in the form of stream data consisting of 0s and 1s, which is stored in the memory and later converted to analog data. It is important to convert the digital data into analog data, because, we can hear only analog signals.
