Abstract
An audio channel system provides an analog signal corresponding to a sound waveform in a computer system. The audio channel system includes a plurality of audio channels. Each audio channel contains a predetermined number of audio data samples for producing a particular sound waveform. A plurality of volume bits define a volume level of each audio data sample to be played. An audio processor processes the sound waveforms of each audio channel. The audio processor acts as a shared processing element which receives the audio data samples from each audio channel. The audio processor divides the audio data samples into a plurality of data such that the plurality of data for each audio data sample is pipelined through the audio processor in a serial manner. The plurality of data for each audio data sample for each audio channel is in various processing stages at any given time. The audio processor combines the data samples and volume bits to produce an audio output signal for each audio channel to produce a total audio output signal.
