Audio formats
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. |
.au | The standard audio file format used by Sun, Unix and Java. The audio in au files can be PCM or compressed with the μ-law, a-law or G729 codecs. |
.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. |
.mp3 | PEG Layer III Audio. It is the most common sound file format used today. |
.msv | A Sony proprietary format for Memory Stick compressed voice files. |
.ogg, .oga, .mogg | A free, open source container format supporting a variety of formats, the most popular of which is the audio format Vorbis. Vorbis offers compression similar to MP3 but is less popular. Mogg, the “Multi-Track-Single-Logical-Stream Ogg-Vorbis”, is the multi-channel or multi-track Ogg file format. |
.raw | A raw file can contain audio in any format but is usually used with PCM audio data. It is rarely used except for technical tests. |
