1. A method for processing audio signals, comprising: (a) storing a representation of at least one audio stream in at least one memory; (b) storing a common instruction sequence in the at least one memory; (c) controlling at least one single-instruction, multiple-data type parallel processor having a plurality of processing cores, to process the at least one audio stream according to the common instruction sequence across the plurality of the processing cores, to perform at least one of frequency transform domain processing, wavelet transform processing, and time-to-frequency domain transform processing, wherein portions of the at least one audio stream are concurrently and synchronously processed according to the common instruction sequence across the plurality of the processing cores, to produce at least one processed audio stream having different audio information than the representation of the at least one audio stream; and (d) storing the at least one processed audio stream in the at least one memory.
