1. A method for generating sound from data following an MPEG encoding standard comprising:

  • transferring a block consisting of independent components of time-domain vectors to a first memory, wherein transferring the block comprises transferring a total of 17 components from a first time-domain vector and 16 components from a second time-domain vector;

    determining products of the independent components in the block with corresponding windowing coefficients;

    accumulating the products in a plurality of sums, each sum corresponding to a different sound amplitude value; and

    generating a sound from the sound amplitude values.
