3-ANNEX C (informative) THE ENCODING PROCESS 3-C.1 Encoder 3-C.1.1 Overview For each of the Layers, an example of one suitable encoder with the corresponding flow-diagram is given in this annex. In subsequent clauses the analysis subband filter and the layer-specific encoding techniques are described. In Annex D two examples of psychoacoustic models, which are common to all layers, are described. A short introduction describes the overall philosophy. INTRODUCTION The MPEG-Audio algorithm is a psychoacoustic algorithm. The figure below shows the primary parts of a psychoacoustic algorithm.
