US 11,443,769 B2 · Enhancing audio using multiple recording devices

Abstract

In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for identifying that a first audio stream includes first, second, and third sources of audio. A computing system identifies that a second audio stream includes the first, second, and third sources of audio. The computing system determines that the first and second sources of audio are part of a first conversation. The computing system generates a third audio stream that combines the first source of audio from the first audio stream, the first source of audio from the second audio stream, the second source of audio from the first audio stream, and the second source of audio from the second audio stream, and diminishes the third source of audio from the first audio stream, and the third source of audio from the second audio stream.

Dependent claims

A computer-implemented method for enhancing audio, the method comprising:

receiving, using a hardware processor, an audio stream for playback on a media device;
extracting, using the hardware processor, a first audio source, a second audio source, and a third audio source from the audio stream;
determining, using the hardware processor, that a conversation between the first audio source and the second audio source occurs within a first portion of the audio stream and a second conversation between the first audio source and the third audio source occurs within a second portion of the audio stream at a second time point;
and
generating, using the hardware processor, an updated audio stream that enhances the first audio source and the second audio source extracted from the first portion of the audio stream and diminishes the third audio source extracted from the first portion of the audio stream and that enhances the first audio source and the third audio source extracted from the second portion of the audio stream and diminishes the second audio source extracted from the second portion of the audio stream.

A system for enhancing audio, the system comprising:

a hardware processor that:
receives an audio stream for playback on a media device;
extracts a first audio source, a second audio source, and a third audio source from the audio stream;
determines that a conversation between the first audio source and the second audio source occurs within a first portion of the audio stream and a second conversation between the first audio source and the third audio source occurs within a second portion of the audio stream at a second time point;
and
generates an updated audio stream that enhances the first audio source and the second audio source extracted from the first portion of the audio stream and diminishes the third audio source extracted from the first portion of the audio stream and that enhances the first audio source and the third audio source extracted from the second portion of the audio stream and diminishes the second audio source extracted from the second portion of the audio stream.

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by a processor, cause the processor to perform a method for enhancing audio, the method comprising:

receiving an audio stream for playback on a media device;
extracting a first audio source, a second audio source, and a third audio source from the audio stream;
determining that a conversation between the first audio source and the second audio source occurs within a first portion of the audio stream and a second conversation between the first audio source and the third audio source occurs within a second portion of the audio stream at a second time point;
and
generating an updated audio stream that enhances the first audio source and the second audio source extracted from the first portion of the audio stream and diminishes the third audio source extracted from the first portion of the audio stream and that enhances the first audio source and the third audio source extracted from the second portion of the audio stream and diminishes the second audio source extracted from the second portion of the audio stream.
