Claim 12:
13. The method of claim 1, wherein applying multi-band compression to the first audio signal includes:
applying a first band-pass filter to the first audio signal to generate a first band-pass filtered audio signal;
applying a second band-pass filter to the first audio signal to generate a second band-pass filtered audio signal, the first band-pass filter and the second band-pass filter associated with different frequency bands;
detecting one or more segments of the first band-pass filtered audio signal having amplitudes exceeding a second threshold;
reducing a dynamic range of the one or more segments of the first band-pass filtered audio signal;
detecting one or more segments of the second band-pass filtered audio signal having amplitudes exceeding a third threshold;
reducing a dynamic range of the one or more segments of the second band-pass filtered audio signal; and
generating the second audio signal using a sum or weighted sum of the first band-pass filtered audio signal and the second band-pass filtered audio signal.
