Abstract

Audio tracks including environmental information are recorded on a DVD, or other playback medium using microphones, vibration sensors, or other devices that capture ambient sound from the original environment in which a performance, presentation or other sound is created. For example, environmental audio tracks can be obtained by placing microphones on the floor, ceiling and walls of an amphitheater during a pop music performance. Any object, item or surface can be a candidate from, or within, which to capture an ambient sound. Sounds can be obtained from sensors mounted to musicians, audience members, theater seats, various rooms within a building, etc. The environmental audio tracks (EATs) can be provided individually or mixed together with one or more other EATs, one or more standard recorded tracks, or otherwise mixed or combined with other sounds. Or the EATs can be processed, effected, etc., as desired. The original or modified EATs are then encoded onto a DVD (or other medium) so that a listener can selectively hear the EATs alone, or in combination with, other audio tracks on the DVD.

Claims

1. A method for providing an audio presentation, the method comprising:

obtaining standard audio track information of a performance;

obtaining environmental information from recordings made during the performance from a plurality of physical locations in the venue;

including the standard audio track information of the performance on a recordable medium as a first set of tracks;

including the obtained environmental information from the recordings made during the performance on the recordable medium as a second set of tracks; and

enabling a user to select, using a playback device including a mixer configured to selectively mix the standard audio track information included in the first set of tracks with the environmental information included in the second set of tracks, whether or not to play the second set of tracks at substantially the same time as the first set of tracks during playback of the standard audio track information included in the first set of tracks to thereby alter, using the environmental information included in the second set of tracks, an audio presentation of the standard audio track information.

2. The method of claim 1, wherein environmental information recorded at a different time then the standard audio track information of the performance is included in the second set of tracks.

3. The method of claim 1, the method further comprising enabling the user to play the second set of tracks separately from the first set of tracks.

4. The method of claim 1, the method further comprising creating a mathematic model of acoustics associated with the venue and including mathematical modeling information in the second set of tracks.

5. The method of claim 1, the method further comprising:

using received playback room characteristics to process the standard audio tracks; and

/or

using received playback room characteristics to process the environmental information.

6. The method of claim 1, wherein the recordings from a plurality of physical locations in the venue include recordings from one or more microphones positioned on a floor, ceiling, or wall.

7. The method of claim 1, wherein the recordings from a plurality of physical locations in the venue include recordings from one or more microphones positioned on one or more corresponding audience members.

8. The method of claim 1, wherein the recordings from a plurality of physical locations in the venue include recordings from one or more vibration sensors.

9. The method of claim 1, wherein the recordings from a plurality of physical locations in the venue include recordings of crowd noise, and where the user can play back the standard audio tracks without the crowd noise.

10. The method of claim 1, wherein the recordings from a plurality of physical locations in the venue include recordings made using at least one microphone that is not present when the performance is recorded.

11. The method of claim 1, wherein the recordable medium is a DVD, and the DVD does not include a video of the performance.

12. The method of claim 1, wherein the audio track information of the performance is streamed over a communication network.

13. The method of claim 1, wherein the audio presentation of the standard audio information is altered during playback by mixing environmental information included in the second set of tracks with the standard audio information in the first set of tracks.

14. A tangible, non-transitory computer-readable medium having computer-executable instructions stored thereon that, if executed by a computing device, cause the computing device to perform a method comprising:

obtaining standard audio track information of a performance;

obtaining environmental information from recordings made during the performance from a plurality of physical locations in the venue;

including the standard audio track information on a recordable medium as a first set of tracks;

including the obtained environmental information on the recordable medium as a second set of tracks; and

enabling a user to select, using a playback device including a mixer configured to selectively mix the standard audio track information included in the first set of tracks with the environmental information included in the second set of tracks, whether or not to play the second set of tracks at substantially the same time as the first set of tracks during playback of the standard audio track information included in the first set of tracks to thereby alter, using the environmental information included in the second set of tracks, an audio presentation of the standard audio track information.

15. The tangible computer-readable medium of claim 14, wherein environmental information recorded at a different time then the standard audio track information of the performance is included in the second set of tracks.

16. The tangible computer-readable medium of claim 14, the method further comprising enabling the user to play the second set of tracks separately from the first set of tracks.

17. The tangible computer-readable medium of claim 14, the method further comprising creating a mathematic model of acoustics associated with the venue and including mathematical modeling information in the second set of tracks.

18. The tangible computer-readable medium of claim 14, the method further comprising:

using received playback room characteristics to process the standard audio tracks; and

/or

using received playback room characteristics to process the environmental information.

19. The tangible computer-readable medium of claim 14, wherein the recordings from a plurality of physical locations in the venue include recordings from one or more microphones positioned on a floor, ceiling, or wall.

20. The tangible computer-readable medium of claim 14, wherein the recordings from a plurality of physical locations in the venue include recordings from one or more microphones positioned on one or more corresponding audience members.
