m4a : MPEG-4 Audio Layer
M4A is an audio file format that is very similar to MP4. It is a proprietary file format of Apple. iTunes store contains the audios as M4A format. It uses MPEG-4 codec to contain audio files. One of the basic differences between M4A and MP4 is M4A does not contain videos like MP4.
PVF is a special low-bandwidth ADPCM-based digital audio format for recording and storing human speech. A .pvf file contains digitally recorded speech in the PVF format. Such .pvf files were mainly used with legacy voice modems and software-based answering machines. Often, to be used with a specific modem, a .pvf file would have to be converted into the device-specific RMD format. Currently, PVF audio files can still be played with several major media players as well as converted into other formats (like WAV) with multi-format converter tools.
