Gapless Gtk-based audio player

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.

The program can play the music through OSS, ALSA or using the 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.
