CD Digital Audio File
A standardized format intended for compact discs. It features an amplitude resolution of 16 bits and a sampling frequency of 44100 Hz. This format emerged back in 1980. It is utilized for storing data on personal computers and CDs. A CS Digital Audio File stores the audio data in the AIFF format. You can see such files if you extract the audio files from a compact disc. This operation can be performed using Apple iTunes.
AMR (Adaptive Multi Rate): adaptive encoding with variable bitrate
This information compression format allows for optimizing speech encoding. Files in the Adaptive Multi Rate format can be created using phones and smartphones. AMR files are mostly used for voice recordings. The main advantages of the format are the large number of encoding and decoding rates, as well as the small size of the resulting content. With the help of appropriate software, an Adaptive Multi Rate file can be converted into any other audio format.
