1. aRts (Analog Real-Time Synthesizer) is a sound system for KDE.aRts creates and processes sound using small modules that do certain tasks. aRts modules can create waveforms (oscillators), playsamples, filter data, add signals, perform effects like delay/flanger/chorus, or output the data to a soundcard. By connecting all of the modules together, you can perform complex tasks like simulating a mixer, generating an instrument, or playing a wave file with effects. From Redhat 8.0 RPM
