Digital surround sound method and apparatus

摘要

Method and apparatus for implementing surround sound in an audio system having a number of audio output devices, and audio output buffers associated with the audio output devices adapted to output audio data in order of receipt. A block of delay data is loaded into a buffer associated with a rear audio output device. Audio data is directed to the audio output devices, by way of the buffers. In the operation of the system, data stored in the buffers is transferred from the buffers to the associated audio output devices. The audio data will be delayed reaching the rear audio output device until the delay data has been output from the buffer resulting in a surround sound effect.
