Abstract

Sound quality is enhanced in a sound system including handsets and headsets. Handset sound enhancing algorithms are implemented in a handset. The handset automatically determines which, if any, of a plurality of headset sound enhancing algorithms are active in a headset in communication with the handset. The handset determines how to use the handset sound enhancing algorithms in a sound processing channel based on which of the headset sound enhancing algorithms are active in the headset.

Claims

1. A method for enhancing sound quality in a communication system, the communication system including a handset in communication with one of a plurality of headsets, the method comprising:

implementing a plurality of handset sound enhancing algorithms in the handset, each handset sound enhancing algorithm operative to be used in a sound processing channel;

automatically determining in the handset which of a plurality of headset sound enhancing algorithms are active in the headset in communication with the handset; and

automatically determining in the handset which handset sound enhancing algorithms to use in the sound processing channel based on the determination of which of the plurality of headset sound enhancing algorithms are active in the headset;

wherein the determination of which handset sound enhancing algorithms to use is made such that duplicative sound enhancement processing in both the handset and the headset is avoided.

2. The method for enhancing sound quality in a communication system as in claim 1 further comprising selectively enabling or disabling at least one headset sound enhancing algorithm in the headset based on a signal received from the handset.

3. The method for enhancing sound quality in a communication system as in claim 1 further comprising adjusting the operation of at least one handset sound enhancing algorithm based on a signal received from the headset.

4. The method for enhancing sound quality in a communication system as in claim 3 wherein the signal received from the headset indicates at least one operating condition of the headset.

5. The method for enhancing sound quality in a communication system as in claim 1 wherein the handset is a first handset, the method further comprising transmitting an indication of the determined first handset sound enhancing algorithms to a second handset.

6. The method for enhancing sound quality in a communication system as in claim 5 further comprising automatically determining in the second handset which second handset sound enhancing algorithms to use in the sound processing channel based on the indication of the determined first handset sound enhancing algorithms transmitted to the second handset.
