ABSTRACT:
Certain aspects of a method and system for implementing a codec may comprise at least one of inverse discrete cosine transforming windowed data corresponding to a plurality of input audio samples during encoding by a Bluetooth subband codec and discrete cosine transforming shifted subband samples during decoding by the Bluetooth subband codec. The input audio samples may be reconstructed from the discrete cosine transforming of the shifted subband samples. The inverse discrete cosine transforming may be executed during a matrix operation of the encoding. The discrete cosine transforming may be executed during a matrix operation of the decoding. The input audio samples may be windowed during the encoding via a plurality of delay lines. A vector may be generated during a matrix operation of the decoding. The audio data associated with the generated vector may be windowed by a plurality of filter coefficients via a plurality of delay lines.
