Abstract
A method and device detect, in an encoder part of a sound codec, an audio band-width of a sound signal to be coded. The device comprises an analyser of the sound signal and a final audio band-width decision module for delivering a final decision about the detected audio band-width using the result of the analysis of the sound signal. In the encoder part, the final audio band-width decision module is located upstream of the sound signal analyser. Also, a method and device switch from a first audio band-width to a second audio band-width of the sound signal. In the encoder part, the device comprises a final audio band-width decision module for delivering a final decision about a detected audio band-width of the sound signal to be coded, a counter of frames where audio band-width switching occurs in response to the detected audio band-width final decision, and an attenuator responsive to the counter of frames for attenuating the sound signal prior to encoding there of.
