Abstract: A method performed by an audio source device that is communicatively coupled with an audio output device, the method includes obtaining an audio signal; receiving a volume adjustment; applying the volume adjustment to the audio signal; applying dynamic range compression on the volume adjusted audio signal; and applying an inverse volume adjustment to the compressed audio signal, where the inverse volume adjusted audio signal is to be transmitted to the audio output device.

Abstract: A power mitigation algorithm in a loudspeaker amplification system that includes a loudspeaker driver, an audio amplifier, and a constant output power, power supply. A power requirement for the amplifier to output an audio signal is determined. A gain adjustment signal is then determined based on a difference between the power requirement and a power budget of the amplifier. Gain of the audio signal is adjusted according to the gain adjustment signal, for output through the loudspeaker driver. As a result, a peak level of the power consumption of the amplifier while outputting the gain-adjusted audio signal becomes less than the power budget. Other embodiments are also described and claimed.

Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may include speaker control circuitry for a speaker. The speaker control circuitry may include multiple parallel prediction blocks that share a single look-ahead delay, and that feed, in parallel, a single controller. The single controller can generate a joint modification to an audio signal based on the parallel outputs of the prediction blocks. The joint modification can then be applied to the audio signal to generate a speaker-protection audio signal that can be output by the speaker. The speaker control circuitry may also include a system modeler that models the speaker system of the electronic device based on feedback measured physical characteristics. In this way, a reduced control safety margin can be achieved by more accurate model predictors, which can allow the controller to safely drive the speaker system to its full capability.

Abstract: An electronic device for buzz reduction is described. The electronic device is to be used with a speaker driver that is built onto an enclosure and is to be driven by an audio signal which could cause the enclosure to produce buzz. The electronic device includes a filter that is to attenuate a frequency component of the audio signal before driving the speaker driver. The electronic device also includes a controller that is to configure the filter to attenuate the frequency component of the audio signal in response to determining that strength of the audio signal at the frequency component exceeds a threshold. Other embodiments are also described and claimed.

Abstract: A method that includes receiving audio content; receiving a volume level at which the audio content is to be played back through a speaker of the headset that is worn by a user; determining a noise level of environmental noise at the headset; determining a noise exposure level by the user based on the volume level, a content level of the audio content, and the noise level; determining whether a content level of the audio content is less than a threshold that is based on the noise exposure level; and responsive to determining that the content level is less than the threshold, adjusting the content level by applying a gain to the audio content such that the gain-adjusted content level of the audio content is at least equal to the noise exposure level.

Abstract: An audio electronics system operates on audio data. A low-pass or bandpass filter produces first data from audio data. A level detector produces a time-varying first gain. The first gain is based on a time-varying level of the first data. A harmonics generator receives, as input, the first data adjusted by an inverse of the first gain. The harmonics generator produces second data, as harmonics of the input. A multiplier outputs the second data adjusted by the first gain. Other aspects are also described and claimed.
