audio processing unit (APU)

The Audio Processing Unit (APU), also known as an audio accelerator, increases the performance ofpersonal computers (PCs) by taking over the processing power for audio signals, like its graphical counterpart, the Graphics Processing Unit (GPU), and thus relieving the central processing unit

. Unlike conventional sound cards, the Audio Processing Unit (APU), which is the central processing component of sound cards, offers a wide range of functions including audio compression and decompression. The APU units' feature set over Digital Signal Processing (DSP) is evident in its advanced APU architecture, which supports multi-channel stereo playback and surround sound. It also supports programming interfaces such as DirectX and sound systems such as Dolby Digital.
