Mono (1.0)
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

Adaptive Multi Rate
This format was originally intended for voice compression and is able to change the bit rates of encoded audio data. AMR is actively used for encoding and decoding voice while its being transmitted over network channels. The format allows one to consider network capacity and adapt it to channel loads. Due to this, the voice quality is practically undiminished.
