Classification: CPC G  H | IPC G

Claim 16:
17. A method of processing an audio signal, comprising:
receiving audio from a playback volume controller/leveler;
discriminating, using signal recognition and classification, between unwanted noise and wanted signal in the audio;
modifying a first or a second dynamic range control compression (DRC) curve, the first DRC compression curve indicating a first amount of gain to apply to the audio and the second DRC compression curved indicating a second amount of gain to apply to the audio, wherein the second amount of gain is different than the first amount of gain, by adjusting, based on the discriminating, a position of one or more knees in the first or the second dynamic range control (DRC) compression curve, and an amount of gain applied to the audio when a level of the audio is below the one or more knees;
comparing the level of the audio with a threshold level;
in accordance with the level of the audio being greater than the threshold level,
processing the audio in accordance with the first DRC compression curve;

in accordance with the level being less than or equal to the threshold level,
processing the audio in accordance with the second DRC compression curve; and

sending the audio to a downstream device.
