Abstract: This disclosure provides methods, devices, and systems for active noise cancellation (ANC). The present implementations more specifically relate to the use of dynamic range compression (DRC) for ANC. In some aspects, an ANC system receives an input audio signal of a transient noise as measured by a microphone, performs DRC on the input audio signal to generate a compressed dynamic range audio signal, and performs ANC on the compressed dynamic range audio signal to generate a cancellation signal associated with the input audio signal. The cancellation signal is based on an adjusted gain of the input audio signal to prevent saturation or large spikes of the cancellation signal, which can cause undesirable audio during playback.

Abstract: Systems and methods for identifying audio events in one or more audio streams include the use of a cascade audio spotting system (such as a cascade keyword spotting system (KWS)) to reduce power consumption while maintaining a desired performance. An example cascade audio spotting system may include a first module and a high-power subsystem. The first module is to receive an audio stream from one or more audio streams, process the audio stream to detect a first target sound activity in the audio stream, and provide a first signal in response to detecting the first target sound activity in the audio stream. The high-power subsystem is to (in response to the first signal being provided by the first module) receive the one or more audio streams and process the one or more audio streams to detect a second target sound activity in the one or more audio streams.
