AUDIO ENCODER

摘要

The invention concerns a audio encoder whereof the first coding stage (6) includes an coding hub (8) receiving a base audio signal (S0) and generating parameters (QS0) coding the base signal and an error signal (E0). A filter bank (9) breaks down the error signals into sub-bands. A second coding stage includes modules (CE0m) respectively coding the error signal sub-band components (E0m), generating parameters (QE0) coding said components. A multiplexer (5) receives the base signal coding parameters and the error signal sub-band components coding parameters, and forms an binary output flow ( PHI ).
