In an audio encoder, such as AAC, the input PCM samples are sent in parallel to an MDCT and a psychoacoustic model that performs again time-to-frequency decomposition with a FFT. To avoid this redundancy, the encoder was restructured to take the output of the MDCT as the input of the psychoacoustic model. Preliminary tests showed that this idea is feasible.: Preprint
