1. A method for processing an audio signal, the method comprising:
- receiving an audio signal;
determining an interference level of the audio signal relative to a threshold interference level; and
processing the audio signal with a lower quality codec or a higher quality codec responsive to the determination of the interference level of the audio signal relative to the threshold interference level.

Abstract
In one embodiment, a method and apparatus for processing an audio signal are provided. In one example of the invention, an audio signal is received. The audio signal is analyzed to determine an interference level of the audio signal relative to a threshold interference level. Then the audio signal is processed with a lower quality codec or a higher quality codec responsive to the determination of the interference level of the audio signal relative to the threshold interference level.
