Abstract

A method for replaying a portion of a multi-party audio interaction to a participant of the audio interaction. A participant of a multi-party audio interaction, such as a conference call or a gaming session, can request a replay of a portion of the audio interaction. A conference processor can provide an outgoing audio stream to the participant that includes a replay audio stream that includes the requested replayed portion of the multi-party audio interaction and a real-time audio stream that includes the ongoing multi-party audio interaction. The replay audio stream can be aurally positioned at an aural position that is different from the real-time audio stream to enhance the participant'"'"'s ability to distinguish between the two audio streams.

Claims

1. A method for replaying a portion of a multi-party audio interaction to a participant of the audio interaction, comprising:

receiving a plurality of incoming audio streams, wherein each of the plurality of incoming audio streams corresponds to one of a plurality of participants of the multi-party audio interaction;

generating an outgoing audio stream comprising a real-time audio stream based on one or more of the plurality of incoming audio streams;

buffering at least one of the plurality of incoming audio streams and the outgoing audio stream in the memory;

continuously providing the outgoing audio stream to a first communication session corresponding to a first participant of the plurality of participants;

receiving a request from the first participant to replay a portion of the multi-party audio interaction;

retrieving the portion of the multi-party audio interaction from the memory;

modifying the portion to generate a replay audio stream that is aurally positioned at a first aural position; and

mixing the replay audio stream into the outgoing audio stream being provided to the first communication session.

2. The method of claim 1 wherein modifying the portion to generate the replay audio stream that is aurally positioned at the first aural position further comprises generating multiple channels of audio signals, wherein the audio signals in at least one of the multiple channels includes frequency and phase characteristics which position the replay audio stream at the first aural position.

3. The method of claim 1 further comprising determining a replay length identifying a length of time of the portion, and wherein retrieving the portion of the multi-party audio interaction further comprises determining a start replay location in the memory based on the replay length and a finish replay location, and the portion comprises a portion of the buffered audio streams contained in the memory between the start replay location and the finish replay location.

4. The method of claim 3 wherein the replay length is provided as a parameter in the request.

5. The method of claim 3 wherein the replay length is maintained in a persistent memory location.

6. The method of claim 5 wherein the replay length is participant configurable.

7. The method of claim 1 further comprising modifying the real-time audio stream to aurally position the real-time audio stream at a second aural position that is different from the first aural position.

8. The method of claim 1 wherein the second aural position is participant configurable.

9. The method of claim 1 further comprising:

generating a second outgoing audio stream comprising a second real-time audio stream based on the one or more of the plurality of incoming audio streams;

continuously providing the second outgoing audio stream to a second communication session corresponding to a second participant of the plurality of participants;

receiving a second request from the second participant to replay a second portion of the conference call;

retrieving the second portion of the multi-party audio interaction from the memory;

modifying the second portion to generate a second replay audio stream that is aurally positioned at a second aural position; and

mixing the second replay audio stream into the second outgoing audio stream being provided to the second communication session concurrently while mixing the modified replay audio stream into the outgoing audio stream being provided to the first communication session.

10. The method of claim 1 wherein continuously providing the outgoing audio stream to the first communication session corresponding to the first participant comprises continuously providing the outgoing audio stream to the first communication session during a period of time that the first participant participates in the multi-party audio interaction.

11. The method of claim 1 wherein a first incoming audio stream of the plurality of incoming audio streams corresponds to the first participant, and wherein receiving the request from the first participant to replay the portion of the multi-party audio interaction comprises detecting in the first incoming audio stream a replay command spoken by the first participant.

12. An apparatus for replaying a portion of a multi-party audio interaction to a participant of the audio interaction, comprising:

a controller; and

a conference processor coupled to the controller and adapted to;

receive a plurality of incoming audio streams, wherein each of the plurality of incoming audio streams corresponds to one of a plurality of participants of the multi-party audio interaction;

generate an outgoing audio stream comprising a real-time audio stream based on one or more of the plurality of incoming audio streams;

buffer at least one of the plurality of incoming audio streams and the outgoing audio stream in the memory;

continuously provide the outgoing audio stream to a first communication session corresponding to a first participant of the plurality of participants;

receive a request from the first participant to replay a portion of the multi-party audio interaction;

retrieve the portion of the multi-party audio interaction from the memory;

modify the portion to generate a replay audio stream that is aurally positioned at a first aural position; and

mix the replay audio stream into the outgoing audio stream being provided to the first communication session.

13. The apparatus of claim 12 wherein the conference processor is further adapted to modify the real-time audio stream to aurally position the real-time audio stream at a second aural position that is different from the first aural position.

14. The apparatus of claim 12 wherein the second aural position is participant configurable.

15. The apparatus of claim 12 wherein the conference processor is further adapted to:

generate a second outgoing audio stream comprising a second real-time audio stream based on one or more of the plurality of incoming audio streams;

continuously provide the second outgoing audio stream to a second communication session corresponding to a second participant of the plurality of participants;

receive a second request from the second participant to replay a second portion of the multi-party audio interaction;

retrieve the second portion of the multi-party audio interaction from the memory;

modify the second portion to generate a second replay audio stream that is aurally positioned at a second aural position; and

mix the second replay audio stream into the second outgoing audio stream being provided to the second communication session concurrently while mixing the modified replay audio stream into the outgoing audio stream being provided to the first communication session.

16. The apparatus of claim 12 wherein a first incoming audio stream of the plurality of incoming audio streams corresponds to the first participant, and wherein to receive the request from the first participant to replay the portion of the multi-party audio interaction the conference processor is further adapted to detect in the first incoming audio stream a replay command spoken by the first participant.
