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.
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:

- Nama – multi-track recorder, mixer and mastering application. Tk and ReadLine interfaces. By Joel Roth (13/01/2010)
- EMi (Ecasound Mastering interface) – virtual rack-mount effect. Python-based. By Felix Le Blanc (27/04/2006)
