US 8,027,482 B2 · DVD audio encoding using environmental audio tracks

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.

Dependent claims

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.
