What is AMR?
The Adaptive Multi-Rate (AMR) standard is a speech coding algorithm that operates on narrowband signals (~200 to 3400 Hz) at variable bit rates in the range of of 4.75 to 12.2 kbps. This technology was initially developed for the GSM system and later adopted by the 3GPP as the mandatory codec for 3G wireless systems based on evolved GSM core networks (WCDMA, EDGE, GPRS). AWB stands for Adaptive Multi-Rate Wideband ACELP speech codec.

What is WAV?
WAV (or WAVE), short for Waveform audio format, is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. Though a WAV file can hold compressed audio (alaw, ulaw, ima adpcm, creative adpcm, microsoft adpcm, mp3 codec etc), the most common WAV format contains uncompressed audio in the linear pulse code modulation (LPCM) format. The standard audio file format for CDs, for example, is LPCM-encoded, containing two channels of 44,100 samples per second, 16 bits per sample.
