Claim One:
1. An apparatus, comprising: a microphone; an analog-to-digital (A/D) converter connected to convert analog sound signals received by the microphone into time domain digital data; a processor connected to process the time domain digital data and to produce time domain digital output, the processor including: a frequency analysis module to convert the time domain digital data into subband digital data; a feature extraction module to determine features of the subband data; an environment detection module to determine one or more sources of the subband data based on a plurality of possible sources identified by predetermined classification parameters; an environment adaptation module to provide adaptations to processing using the determination of the one or more sources of the subband data; a subband signal processing module to process the subband data using the adaptations from the environment adaptation module; and a time synthesis module to convert processed subband data into the time domain digital output.
