Abstract

A system and method for dynamically establishing optimum audio quality in an audio conference is disclosed. A connection with one or more remote communication devices is initially established. An available data rate associated with the connection is then determined. Next, a bandwidth is assigned based on the available data rate. Finally, the assigned bandwidth is adjusted according to the available data rate.

Claims (29)

1. A method of conducting an audio conference, comprising:

establishing a connection between a local communication device and one or more remote communication devices for conducting the audio conference;

determining an available data rate associated with the connection;

assigning an audio quality based on the available data rate; and

adjusting the audio quality in response to changes to the available data rate.

2. The method of claim 1 , wherein adjusting the audio quality is proportional to the changes to the available data rate.

3. The method of claim 1 , wherein the adjusting is in response to received audio quality feedback.

4. The method of claim 1 , wherein the adjusting occurs at the beginning of the audio conference.

5. The method of claim 1 , wherein the adjusting occurs during the audio conference.

6. The method of claim 1 , wherein the one or more remote communication devices is a conferencing system, a bridge or a telephone.

7. The method of claim 1 , wherein the adjusting comprises changing the band of frequencies encoded by an audio encoder.

8. A method of conducting an audio conference, comprising:

establishing a connection between a local communication device and one or more remote communication devices for conducting the audio conference;

determining an available data rate associated with the connection;

encoding audio having a bandwidth of frequencies wherein the bandwidth is selected based on the data rate;

transmitting the encoded audio via the connection; and

adjusting the bandwidth in response to a change in the available data rate.

9. The method of claim 8 , wherein the one or more remote communication devices is a conferencing system, a bridge or a telephone.

10. A method for dynamically establishing optimum audio quality in an audio conference, comprising:

establishing a connection, by a local communication device, with one or more remote communication devices for conducting the audio conference;

determining an available data rate associated with the connection;

assigning an audio bandwidth based on the available data rate; and

adjusting the audio bandwidth proportionally to changes to the available data rate.

11. The method of claim 10 , wherein the adjusting occurs at the beginning of the audio conference.

12. The method of claim 10 , wherein the adjusting occurs during the audio conference.

13. The method of claim 10 , wherein the one or more remote communication devices is a conferencing system, a bridge or a telephone.

14. The method of claim 10 , wherein the connection is an analog connection or a digital connection.

15. The method of claim 10 , wherein the audio bandwidth is adjusted in response to received audio quality feedback.

16. The method of claim 10 , wherein the audio bandwidth is adjusted to narrowband.
