1. an audio effects pedal application Using ecasound libraries, this program provides a real-time effects pedal simulated in an X screen. It can read from the audio device, and output to an audio device in real time, or can process wave files. It can work very flexibly. For more complex interface, see ecawave, and qtecawave. For command-line addicts, this is not the way to go, go for ecasound. It can apply any ladspa plugin to the audio data. From Debian 3.0r0 APT
