Patent ID: 7636435

Claim:
A device for processing audio signals for telecommunication equipment, comprising: automatic gain control means configured for: calculating an overall coefficient as a function of a level of a received audio signal, and; acting on the level of the received audio signal by amplifying and attenuating said received audio signal according to said coefficient; the device further comprising: echo cancelling means; the automatic gain control means comprising: amplification means acting downstream of said echo cancelling means; and attenuation means acting upstream of said echo cancelling means, the amplification and attenuation means for separately amplifying and attenuating the received audio signal with respect to the propagation direction of the received audio signal, and said automatic gain control means further being configured for: controlling the amplification means for applying the overall coefficient when said coefficient is an amplification coefficient; and controlling the attenuation means for applying the overall coefficient, when said coefficient is an attenuation coefficient.
