1. A method for adapting acoustic processing in a communication device, the method comprising:
- capturing, using multiple microphones of the communication device, at least one acoustic signal having captured ambient sound;
determining, for the captured ambient sound, a frequency domain transfer function between a pair of the multiple microphones;
comparing at least a portion of the frequency domain transfer function to stored transfer functions for different acoustic environments to select an acoustic environment; and
adapting acoustic processing within the communication device based on the selected acoustic environment.
