Claims18
A method of adaptive multiband gain control, responsive to a background audio signal, the method including:
- receiving a signal representing the background audio signal;
- estimating signal power of the background audio signal in n subbands, where n>=2;
- and
- extrapolating from the n subband signal power estimates to m subband gain control signal power estimates, where m>n.
