Abstract
A system and method are provided herein for dynamically adjusting delay in an audio distribution system, the method comprising: determining what audio processing devices comprise each of a plurality of audio data channels, wherein each of the plurality of audio data channels comprises a path from a digital audio receiving device to a back end audio playing device; obtaining digital audio processing delays for each of the audio processing devices for each of the audio data channels; determining which of the audio data channels has the greatest delay in processing and transmitting digital audio data signals (digital audio data processing delay) prior to broadcasting the digital audio data signals as acoustic audio signals; determining a difference between the audio data channel with the greatest digital audio data processing delay and each of the remaining audio data channels (delay difference per channel); and adding a delay to each digital audio word in each different audio channel that substantially equalizes the digital audio data processing delay between each of the different audio data channels.
