Abstract
Disclosed implementations for determining a reverb characteristic of an environment. An audio signal capturing an amount of sound emitted from a source within an environment over a period of time is received from an audio sensor. A reverb parameter measuring a decrease in the sound over the period of time and a measure of the amount of sound that includes background noise in the environment are determined. The reverb characteristic of the environment is determined based on the reverb parameter and the measure. Spatial audio then rendered based on the reverb characteristic.
Claims27
A non-transitory computer readable medium having stored thereon executable instructions that, when executed by an electronic processor, cause the electronic processor to perform operations comprising:
- receiving, from an audio sensor, an audio signal capturing an amount of sound emitted from a source within an environment over a period of time;
- determining a reverb parameter measuring a decrease in the sound over the period of time;
- determining a measure of the amount of sound that includes background noise in the environment;
- determining a reverb characteristic of the environment based on the reverb parameter and the measure;
- and
- rendering spatial audio based on the reverb characteristic.
A method comprising:
- receiving, from an audio sensor, an audio signal capturing an amount of sound emitted from a source within an environment over a period of time;
- determining a reverb parameter measuring a decrease in the sound over the period of time;
- determining a measure of the amount of sound that includes background noise in the environment;
- determining a reverb characteristic of the environment based on the reverb parameter and the measure;
- and
- rendering spatial audio based on the reverb characteristic.
A system comprising:
- an audio sensor;
- at least one speaker;
- and
- an electronic processor coupled to the audio sensor and the at least one speaker, the electronic processor configured to perform operations comprising:
- receiving, from the audio sensor, an audio signal capturing an amount of sound emitted from a source within an environment over a period of time;
- determining a reverb parameter measuring a decrease in the sound over the period of time;
- determining a measure of the amount of sound that includes background noise in the environment;
- determining a reverb characteristic of the environment based on the reverb parameter and the measure;
- and
- rendering spatial audio via the at least one speaker based on the reverb characteristic.
