PROCESSING IN THE ENCODED DOMAIN OF AN AUDIO SIGNAL ENCODED BY ADPCM CODING

摘要

A method for processing an encoded audio signal in a binary stream by MICDA predictive coding. The method includes the following steps: determining a signal assessed from quantification indices of the binary stream; determining unencoded parameters representative of the audio signal from the assessed signal; and processing the encoded audio signal using the determined parameters. Also provided is a device implementing the method.

1. A method for processing a coded audio signal in a bitstream by a predictive coding of ADPCM type, wherein the method comprises the following steps:
determination by a processing device of an estimated signal on the basis of quantization indices of the bitstream; determination by the processing device of uncoded parameters representative of said audio signal, on the basis of said estimated signal; and processing of said coded audio signal by the processing device using the parameters determined.
