Abstract: Implementations of the subject technology provide systems and methods for providing environment-based audio processing for audio devices. Environment-based audio processing may include identifying an environmental condition in a physical environment of an audio device, and deactivating one or more digital signal processors and/or neural networks based on the environmental condition.

Abstract: Aspects of the subject technology provide for identifying a portion of one or more audio signals from one or more microphones of an electronic device that correspond to a sound-generating component of the electronic device. The identification of the portion of the audio signals may be based on a near-field impulse response for the sound-generating component and the one or more microphones. The electronic device may then be operated based on the audio signals and the identified portion of the audio signals. The sound-generating component may be a speaker, and operating the electronic device based on the audio signals and the identified portion of the audio signals may include performing a residual echo suppression by removing the identified portion of the audio signals from the audio signals, and transmitting, storing, and/or otherwise processing the residual echo suppressed audio signals.

Abstract: Aspects of the subject technology relate to determining a location of a device using sound that is output from the device. For example, an audio output from one or more speakers of an electronic device may be received at one or more microphones of another electronic device, and used by the other electronic device to determine the location of the electronic device.

Abstract: A plurality of microphone signals of a microphone array may be obtained. An environment change may be detected based on the microphone signals. In response, a reverberation time environment may be determined. The reverberation may be used to modify a playback audio signal.
