A method includes determining one or more audio characteristics of a first digital signal representing a first portion of streaming media content provided by a media playback application to an audio output component; playing the first portion of the media content into an environment; capturing, by an audio output component, a second digital signal representing the first portion of the media content as played; determining, based on the captured second digital signal, one or more detected audio characteristics of the media content as played into the environment; determining a difference between the one or more audio characteristics of the media content and the one or more detected audio characteristics; calibrating a second portion of the media content based on the difference and based on a determination that the second portion is to be calibrated; and playing, by the audio output component into the environment, the second portion as calibrated.

Real-time adaptation of audio playback

A method includes providing, for each respective audio channel of a plurality of audio channels provided by an operating system of a computing device, a set of successive audio processing stages to apply to the respective audio channel. The method also includes providing, by the operating system, an application programming interface (API) configured to set a plurality of parameters for adjusting the set of successive audio processing stages for each respective audio channel. The method additionally includes receiving, via the API and from an application running on the computing device, one or more values for one or more parameters of the plurality of parameters. The method further includes adjusting, by the operating system, the plurality of audio channels based on the received one or more values for the one or more parameters.

Dynamics processing effect architecture

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for suppressing hotword triggers when detecting a hotword in recorded media are disclosed. In one aspect, a method includes the actions of receiving, by a computing device, audio corresponding to playback of an item of media content. The actions further include determining, by the computing device, that the audio includes an utterance of a predefined hotword and that the audio includes an audio watermark. The actions further include analyzing, by the computing device, the audio watermark. The actions further include based on analyzing the audio watermark, determining, by the computing device, whether to perform speech recognition on a portion of the audio following the predefined hotword.

Recorded media hotword trigger suppression

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using audio watermarks with key phrases. One of the methods includes receiving, by a playback device, an audio data stream; determining, before the audio data stream is output by the playback device, whether a portion of the audio data stream encodes a particular key phrase by analyzing the portion using an automated speech recognizer; in response to determining that the portion of the audio data stream encodes the particular key phrase, modifying the audio data stream to include an audio watermark; and providing the modified audio data stream for output.

Key phrase detection with audio watermarking

In some embodiments, an ear-mounted sound reproduction system is provided. The system includes an ear-mountable housing that sits within the pinna of the ear and occludes the ear canal. In some embodiments, the ear-mountable housing includes a plurality of external-facing microphones. Because the external-facing microphones may be situated within the pinna of the ear but outside of the ear canal, the microphones will experience some, but not all, of the three-dimensional acoustic effects of the pinna. In some embodiments, sound is reproduced by an internal-facing driver element of the housing using a plurality of filters applied to the signals received by the plurality of external-facing microphones to preserve three-dimensional localization cues that would be present at the eardrum in the absence of the housing, such that the housing is essentially transparent to the user. In some embodiments, techniques are provided for deriving the plurality of filters.
