| 1. A method for compressing a sampled input signal having a plurality of signal samples with a dynamic range and a sample
rate, comprising:
setting a characteristic of a control function in memory;
applying the control function to determine a sample rate control parameter and a dynamic range control parameter in accordance
with the characteristic of the control function;
processing the signal samples to reduce the dynamic range and downsample the signal samples in response to the dynamic range
control parameter and the sample rate control parameter to produce modified signal samples; and
encoding the modified signal samples to produce compressed samples.
