SoundConverter is the leading audio file converter for the GNOME
Desktop. It reads anything GStreamer can read (Ogg Vorbis, AAC, MP3,
FLAC, WAV, AVI, MPEG, MOV, M4A, AC3, DTS, ALAC, MPC, Shorten, APE,
SID, MOD, XM, S3M, etc...), and writes to Opus, Ogg Vorbis, FLAC, WAV,
AAC, and MP3 files, or use any GNOME Audio Profile.
SoundConverter aims to be simple to use, and very fast. Thanks to its
multithreaded design, it will use as many cores as possible to speed
up the conversion. It can also extract the audio from videos.
