Efficient load sharing and accelerating of audio post-processing

A media player device comprising:

• a first processor configured with a plurality of post-processing modules to alter decoded audio signals,
• a second processor configured with a plurality of associated post-processing modules that correspond with the plurality of post-processing modules from the first processor,
• an optimized acceleration module configured to transfer a buffer packet of a decoded audio signal from the first processor to the second processor via a single data path, and to receive a post-processed buffer packet of the decoded audio signal from the second processor back to the first processor via a single return data path, and
• an audio output device controlled by the first processor and configured to render the post-processed buffer packet of the decoded audio signal.

A non-transitory, tangible computer readable storage medium, encoded with processor readable instructions to perform a method for audio post-processing, the method comprising:

• receiving, at a first processor, a decoded audio signal;
• detecting, at the first processor, a plurality of post-processing modules for altering the decoded audio signal,
• creating, based on information identifying functions of the plurality of post-processing modules, an optimized acceleration module;
• sending, through the optimized acceleration module, a buffer packet of the decoded audio signal along a single data path to a second processor;
• post-processing, at the second processor, the buffer packet of the decoded audio signal through each of a plurality of associated post-processing modules that correspond to the post-processing modules on the first processor;
• controlling each associated post-processing module via control paths from each corresponding post-processing module;
• receiving, at the first processor, a post-processed buffer packet of the decoded audio signal via a single return data path.
