Description:

Ecasound is a software package designed for multitrack audio
processing. It can be used for simple tasks like audio playback,
recording and format conversions, as well as for multitrack effect
processing, mixing, recording and signal recycling. Ecasound supports
a wide range of audio inputs, outputs and effect algorithms. Several
open-source audio packages, like for instance ALSA, OSS, mpg123, lame
and MikMod, are directly supported. One of the advantages of
ecasound's chain-based design is that effects can easily be combined
both in series and in parallel. Oscillators and MIDI-CCs can be used
for controlling effect parameters. Included user-interfaces are
ecasound - a versatile console mode interface, ecawave - a Qt-based
X-interface and various command-line utils suitable for batch
processing.
