+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. Effects and audio objects can be combined in
+various ways, and their parameters can be controlled by operator objects like
+oscillators and MIDI-CCs. A versatile console mode user-interface is included
+in the package.")
