Ecasound is a hard-disk recording and audio processing tool for Unix-like computer operating systems including Linux, Mac OS X, and FreeBSD.

Ecasound allows flexible interconnection of audio inputs, files, outputs, and effects algorithms, realtime-controllable by builtin oscillators, MIDI, or interprocess communication via GUI front-end. Ecasound supports JACK and LADSPA effects plug-ins.

The team leader is Kai Vehmanen, with dozens of contributors. Kai joined the project in 1995, when it was called "wavstat", a simple DSP utility running under OS/2. Available under the GNU General Public License, Ecasound is free software.

User Interface

Ecasound is a command-line tool: it does not include a native graphical interface. Major tasks (recording, mixdown) can be easily performed directly from the command line interface, or by scripts. Several GUI front-ends have been written for it:
