A special processor circuit that is designed to perform complex operations on audio waveforms. This specialization permits sophisticated sounds to be produced rapidly and efficiently. This architecture may be compared with video and graphic processor circuits that have been used to accelerate and improve video output. DSP is used in sound cards, or audio equipment to create soundfields which are electronic or digitally synthesized acoustical environments for audio enhancement, and to create time delays and for precise steering of multi-channel Dolby Pro Logic information.
