Aqualung is an advanced music player originally targeted at the GNU/Linux operating system, today also running on FreeBSD, OpenBSD and Microsoft Windows. It plays audio CDs, internet radio streams and podcasts as well as soundfiles in just about any audio format 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.

Audio CDs can be played back and ripped with on-the-fly conversion to WAV, FLAC, Ogg Vorbis or CBR/VBR MP3 (gapless via LAME). Seamless tagging of the created files is offered as part of the process. Internet radio stations streaming Ogg Vorbis or MP3 are supported. Subscribing to RSS and Atom audio podcasts is supported: Aqualung can automatically download and add new files to the Music Store. Optional limits for the age, size and number of downloaded files can be set.

Aqualung has a large number of configuration settings, which are adjustable through the user interface at run-time (no need to edit config files by hand), and are remembered across multiple invocations of the program.
