Abstract

Disclosed herein are system, method, and computer program product embodiments for replicating a remote venue in a local venue. An embodiment operates by receiving original audio. Thereafter, the original stream of audio is modified to produce modified audio based on an audio profile unique to a remote venue smaller than the local venue. The audio profile comprises a virtual representation of the remote venue including (i) a virtual audio source corresponding to the local venue's audio source and configured to produce the original audio and (ii) a virtual reverberation point corresponding to a real-world location in the remote venue and the portion of the local venue. As such, the modified audio is determined based on receipt of the original audio from the reverberation point. Thus, after correlating the modified audio to the local venue's audio source, the modified audio is provided by the audio source to the portion of the local venue.

First claim

What is claimed is:

1 . A method for developing an audio profile for sound traveling through a venue, the method comprising:
identifying, by a computer system, a plurality of reflection points and a plurality of reverberation points within the venue, each reverberation point from among the plurality of reverberation points being a distance away from a corresponding reflection point from among the plurality of reflection points; directing the sound from a first location within the venue toward a first reflection point from among the plurality of reflection points; and analyzing, by the computer system, the sound as received at the first reflection point and a first reverberation point from among the plurality of reverberation points that corresponds to the first reflection point to develop the audio profile for the venue.

2 . The method of claim 1 , further comprising:
determining, by the computer system, an origin point with the venue that corresponds to a middle point of a stage within the venue, and wherein the first location within the venue comprises the origin point.

3 . The method of claim 1 , wherein the identifying comprises:
identifying a first plurality of locations of the plurality of reflection points within the venue, the first plurality of locations being based on a second plurality of locations of a plurality of audio sources within a second venue that is different from the venue.

4 . The method of claim 3 , wherein the identifying further comprises:
identifying a third plurality of locations of the plurality of reverberation points within the venue, the third plurality of locations corresponding to the second plurality of locations of the plurality of audio sources within the second venue, wherein a number of reverberation points from among the plurality of reverberation points is less than a number of audio sources from among the plurality of audio sources when the second venue is smaller than the venue, and wherein the number of reverberation points from among the plurality of reverberation points is greater than the number of audio sources when the second venue is larger than the venue.

5 . The method of claim 1 , wherein the analyzing comprises:
analyzing, by the computer system, the sound as received at a second reflection point from among the plurality of reflection points and a second reverberation point that corresponds to the second reflection point from among the plurality of reverberation points to develop the audio profile for the venue.

6 . The method of claim 1 , wherein the directing comprises:
directing the sound from the first location within the venue at a sound pressure level (SPL) selected from a plurality of SPLs at a frequency within a predetermined frequency range.

7 . The method of claim 1 , further comprising:
directing a second sound from a second location within the venue toward the first reflection point; and analyzing the second sound as received at the first reflection point and the first reverberation point to develop the audio profile for the venue.

8 . The method of claim 1 , wherein the analyzing comprises:
measuring a reverberation of the sound at the first reverberation point, wherein a duration of the reverberation of the sound is based upon a real-world characteristic of the venue.

9 . A computer system developing an audio profile for sound traveling through a venue, the computer system comprising:
a memory that stores instructions; and a processor configured to execute the instructions stored in the memory, the instructions, when executed by the processor, configuring the processor to:
identify a plurality of reflection points and a plurality of reverberation points within the venue, each reverberation point from among the plurality of reverberation points being a distance away from a corresponding reflection point from among the plurality of reflection points, and
analyze a sound, directed from a first location within the venue toward a first reflection point from among the plurality of reflection points, as received at the first reflection point and a first reverberation point from among the plurality of reverberation points that corresponds to the first reflection point to develop the audio profile for the venue.

10 . The computer system of claim 9 , wherein the instructions, when executed by the processor, further configure the processor to:
determine an origin point with the venue that corresponds to a middle point of a stage within the venue, and wherein the first location within the venue comprises the origin point.

11 . The computer system of claim 9 , wherein the instructions, when executed by the processor, configure the processor to identify a first plurality of locations of the plurality of reflection points within the venue, the first plurality of locations being based on a second plurality of locations of a plurality of audio sources within a second venue that is different from the venue.

12 . The computer system of claim 11 , wherein the instructions, when executed by the processor, configure the processor to identify a third plurality of locations of the plurality of reverberation points within the venue, the third plurality of locations corresponding to the second plurality of locations of the plurality of audio sources within the second venue,
wherein a number of reverberation points from among the plurality of reverberation points is less than a number of audio sources from among the plurality of audio sources when the second venue is smaller than the venue, and wherein the number of reverberation points from among the plurality of reverberation points is greater than the number of audio sources when the second venue is larger than the venue.

13 . The method of claim 9 , wherein the instructions, when executed by the processor, further configure the processor to analyze the sound as received at a second reflection point from among the plurality of reflection points and a second reverberation point from among the plurality of reverberation points that corresponds to the second reflection point to develop the audio profile for the venue.

14 . The computer system of claim 9 , wherein the sound is configured to be at a sound pressure level (SPL) selected from a plurality of SPLs at a frequency within a predetermined frequency range.

15 . The computer system of claim 9 , wherein the instructions, when executed by the processor, further configure the processor to
analyze a second sound, directed from a second location within the venue toward the first reflection point, as received at the first reflection point and the first reverberation point to develop the audio profile for the venue

16 . The computer system of claim 9 , wherein the instructions, when executed by the processor, further configure the processor to measure a reverberation of the sound at the first reverberation point, and
wherein a duration of the reverberation of the sound is based upon a real-world characteristic of the venue.

17 . A system for developing an audio profile for sound traveling through a venue, the system comprising:
a first plurality of audio receivers at a plurality of reflection points within the venue; a second plurality of audio receivers at the plurality of reflection points, each reverberation point from among the plurality of reverberation points being a distance away from a corresponding reflection point from among the plurality of reflection points; an audio source configured to direct the sound from a first location within the venue toward a first
