Here are the most recurrent audio formats we deal with:

Supported File Extensions File Details
.aa low-bitrate audiobook container format with DRM, containing audio encoded as either MP3 or the ACELP speech codec.
.ape Monkey’s Audio lossless audio compression format.

.m4a An audio-only MPEG-4 file, used by Apple for unprotected music downloaded from their iTunes Music Store. Audio within the m4a file is typically encoded with AAC, although lossless ALAC may also be used.
