Abstract
The present invention generally provides a way to analyze crowd noise to identify “highlights” or the like. Specifically, an audio stream containing crowd noise from an event (e.g., sporting event, political rally, religious gathering, etc) is captured (e.g., using microphones) and time coded. The audio stream is normalized based on geography and processed to remove undesired artifacts and to identify a set (at least one) of highlights. Based on at least one threshold, at least one highlight is selected from the set of highlights.
Claims25
A method for analyzing crowd noise, comprising:
- receiving an audio stream for an event, the audio stream containing crowd noise;
- time coding the audio stream;
- normalizing the audio stream based on geography;
- and
- processing the audio stream to remove undesired artifacts and to identify a set of highlights from the crowd noise.
The method 1, the normalizing comprising comparing a geographic characteristic of a participant of the event to a geographic characteristic of the event to identify a home participant of the event.
A system for analyzing crowd noise, comprising:
- a module for receiving an audio stream for an event, the audio stream containing crowd noise;
- a module for time coding the audio stream;
- a module for normalizing the audio stream based on geography;
- and
- a module for processing the audio stream to remove undesired artifacts and to identify a set of highlights from the crowd noise.
The system 9, the module for normalizing being configured to:
- compare a geographic characteristic of a participant of the event to a geographic characteristic of the event to identify a home participant of the event.
A program product stored on a computer readable medium for analyzing crowd noise, the computer readable medium comprising program code for causing a computer system to:
- receive an audio stream for an event, the audio stream containing crowd noise;
- time code the audio stream;
- normalize the audio stream based on geography;
- and
- process the audio stream to remove undesired artifacts and to identify a set of highlights from the crowd noise.
The program product 17, the computer readable medium further comprising program code for causing the computer system to:
- compare a geographic characteristic of a participant of the event to a geographic characteristic of the event to identify a home participant of the event.
A method for deploying a system for analyzing crowd noise, comprising:
- providing a computer infrastructure being operable
- receive an audio stream for an event, the audio stream containing crowd noise;
- time code the audio stream;
- normalize the audio stream based on geography;
- and
- process the audio stream to remove undesired artifacts and to identify a set of highlights from the crowd noise.
