1. A method for audio processing, comprising:
- receiving a first acoustic signal from a microphone;
receiving information from a first non-acoustic sensor, the first non-acoustic sensor information including a measured spatial position or measured change in position of the microphone relative to a spatial position of a desired audio source; and
executing a module by a processor, the module executable to determine a set of parameters to use to modify the first acoustic signal based on the first acoustic signal and the first non-acoustic sensor information, the modifying being at least one of noise suppression, echo cancellation, audio source separation, and equalization.

Abstract
An audio processing system processes an audio signal that may come from one or more microphones. The audio processing system may use information from one or more non-acoustic sensors to improve a variety of system characteristics, including responsiveness and quality. Those audio processing systems that use spatial information, for example to separate multiple audio sources, are undesirably susceptible to changes in the relative position of any audio sources, the audio processing system itself, or any combination thereof. Using the non-acoustic sensor information may decrease this susceptibility advantageously in an audio processing system.

11. A system for audio processing, comprising:
-
a first microphone that transduces a first acoustic signal, wherein the first acoustic signal includes a desired component and an undesired component; a first non-acoustic sensor that provides non-acoustic information, the non-acoustic information including a measured spatial position or measured change in position of the microphone relative to a spatial position of a desired audio source; and one or more executable modules for determining a set of parameters to use to modify the first acoustic signal based on the first acoustic signal and the non-acoustic sensor information, the modifying being at least one of noise suppression, echo cancellation, audio source separation, and equalization. - View Dependent Claims (12, 13, 14, 15, 16, 20)
