ACS (Audio Components Suite) is a freeware cross-platform set of components designed to perform different sound-processing tasks. It supports reading the audio data from CD, different file formats, for example wav,mp3,wma,ogg,mac and others, output to soundcard and files is also possible. Between input and output you can work with the data, different converters, mixers and processors are available.

Its main characteristics are :

• Abstract Layer to include different "drivers"
  • Alsa, /dev/dsp, AOLive, OSS support within Linux
  • DirectX, Wavemapper support within Windows
  • Audio playback and capture
  • Simultaneous operations on the same or different devices are allowed.
