This page describes some audio formats and how to use them in Debian
Ogg
Ogg is a free, open container format maintained by the Xiph.Org Foundation. It is unrestricted by software patents and designed to provide for efficient streaming and manipulation of high-quality digital multimedia. The Ogg container format can multiplex a number of independent streams for audio, video, text (such as subtitles), and metadata.
Many programs in Debian support Ogg playback/recording. Use vorbis-tools for command line manipulation of Ogg files.
Ogg can encapsulate various audio and video formats: Opus Vorbis FLAC Speex CELT Theora Dirac
mp3
MP3 is an audio coding format for digital audio.
MP3 is a widely supported, lossy audio compression format with a lower compression ratio than Ogg.
Convert a mp3 to an audio CD track with mpg321: mpg321 --cdr my_track.cdr my_track.mp3
Convert all mp3 files to CD tracks: =1; for f in *.mp3; do mpg321 --cdr /tmp/$(printf %02d.cdr $i) "$f"; let i++; done
AAC
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. It was designed to be the successor of the MP3 format and generally achieves higher sound quality than MP3 at the same bit rate. AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications.
Many multimedia tools in Debian support this format either using recent FFmpeg native AAC support or the Free AAC (FAAC) implementation (faac, faad), and the Fraunhofer FDK AAC codec for Android (fdk-aac)
