摘要 |
The invention relates to a method of control of a processing of attenuation of quantization noise of a decoded digital audio signal, the quantization noise being generated by a compression coding comprising a quantization operation. The method comprises a step of obtaining (E201) an estimation of the quantization noise on the basis of a signal available to the decoder and is such that it comprises the following steps: - determination (E202) of a psycho-acoustic criterion on the basis of a signal available to the decoder; - determination (E203), per signal frame, of a level of attenuation to be applied to the noise attenuation processing (E204) of the decoded signal, as a function of the estimation of the quantization noise and of the determined psycho-acoustic criterion. The invention relates also to a control device implementing the method described and to a processing device comprising such a device. |
