Claim:
1. A method for decoding an encoded digital audio signal containing audio data and a plurality of metadata parameters, comprising: demultiplexing the encoded digital audio signal to unpack the plurality of metadata parameters from the encoded digital audio signal and separate the audio data into a plurality of audio channels; decoding and processing the plurality of metadata parameters to determine which channels of the plurality of audio channels are to be filtered to obtain selected channels; decoding the audio data of the encoded digital audio signal to obtain a decoded audio signal; processing the selected channels of the plurality of audio channels to include a spatially diffuse effect to obtain filtered audio channels; receiving playback parameters defining a unique local acoustic environment that impacts the spatially diffuse effect to compensate for spatially diffuse deviations that occur when the decoded audio signal is played back in the unique local acoustic environment; mixing the filtered audio channels based on the plurality of metadata parameters and the playback parameters to obtain output audio channels; and playing back the output audio channels in the unique local acoustic environment.
