Product : Fedora Core 3
Name : arts
Version : 1.4.2
Release : 0.fc3.2
Summary : A modularized sound system for KDE.
Description :
aRts (Analog Real-Time Synthesizer) is a sound system for KDE
2.x. aRts creates and processes sound using small modules that do
certain tasks. aRts modules can create waveforms (oscillators), play
samples, filter data, add signals, perform effects like
delay/flanger/chorus, or output the data to the soundcard.

By connecting all those small modules together, you can perform
complex tasks like simulating a mixer, generating an instrument, or
playing a wave file with effects.
