Aqualung is a music player for the GNU/Linux operating system. It plays
audio files from your filesystem and has the feature of inserting no gaps
between adjacent tracks. It also supports high quality sample rate
conversion between the file and the output device, when necessary.

Almost all sample-based, uncompressed formats (e.g. WAV, AIFF, AU etc.)
are supported. Files encoded with FLAC (the Free Lossless Audio Codec),
Ogg Vorbis, Ogg Speex, MPEG Audio (including the infamous MP3 format) and
MOD audio formats (MOD, S3M, XM, IT, etc.), Musepack are also supported.

Ce programme peut jouer de la musique à travers OSS, ALSA ou en utilisant
JACK Audio Connection Kit.

Aqualung supports the LADSPA 1.1 plugin standard. You can use any suitable
plugin to enhance the music you are listening to.
