Abstract
A method, and system, of digital room correction for a device, such as a smart speaker, including a loudspeaker. The method comprises capturing audio from an environment local to the device, for example from one or more microphones of a smart speaker. The captured audio is then processed to recognize one or more categories of sound. A digital room correction procedure may then be controlled dependent upon recognition and/or analysis of at least one of the categories of sound.
Claims14
A method of digital room correction for a device including a loudspeaker, the method comprising:
- capturing audio, using one or more microphones associated with the device, from an environment local to the device;
- processing the captured audio to recognize one or more categories of sound;
- and
- in response to recognizing the one or more categories of sound:
- controlling, by the device, a digital room correction procedure comprising determining a room response correction dependent upon analyzing captured audio associated with the at least one of the categories of sound, the analyzing comprising characterizing a modification of the captured audio caused by the environment local to the device.
A method of controlling sound generation by a device including a loudspeaker, the method comprising:
- capturing audio, using one or more microphones associated with the device, from an environment local to the device;
- inputting a play audio data stream representing audio to be played by the device;
- generating sound from the device according to the play audio modified by a speaker response;
- processing the captured audio to recognize one or more categories of sound;
- and
- in response to recognizing the one or more categories of sound:
- adjusting the speaker response by controlling a digital room correction comprising determining a room response correction dependent upon analyzing captured audio associated with the at least one of the categories of sound, the analyzing comprising characterizing a modification of said captured audio caused by the environment local to the device.
A method of digital room correction for a device including a loudspeaker, the method comprising:
- capturing audio, using one or more microphones associated with the device, from an environment local to the device;
- processing the captured audio to recognize one or more categories of sound;
- and
- in response to recognizing the one or more categories of sound:
- controlling, by the device, a digital room correction procedure dependent upon recognition at of least one of the categories of sound and/or analysis of captured audio associated with the at least one of the categories of sound, wherein the controlling the digital room correction comprises at least one of:
- suppressing operation of the digital room correction;
- and
- adjusting audio played by the loudspeaker of the device comprising modifying frequencies and/or times of sounds generated by the device in response to a determination that said frequencies and/or times are predicted to require modification based on environmental audio from the environment local to the device.
