Abstract: Various aspects of the present disclosure generally relate to haptic feedback. In some aspects, a device may receive an input identifying a one-cycle induced acceleration waveform associated with a haptic device, a resonant frequency associated with the haptic device, and a target acceleration waveform for the haptic device. The device may determine a plurality of weights based at least in part on the input. The device may generate a playback waveform based at least in part on the plurality of weights. The device may provide the playback waveform as input to the haptic device. Numerous other aspects are provided.

Abstract: A device includes a memory configured to store instructions and one or more processors configured to execute the instructions. The one or more processors are configured to execute the instructions to receive audio data including a first audio frame corresponding to a first output of a first microphone and a second audio frame corresponding to a second output of a second microphone. The one or more processors are also configured to execute the instructions to provide the audio data to a first noise-suppression network and a second noise-suppression network. The first noise-suppression network is configured to generate a first noise-suppressed audio frame and the second noise-suppression network is configured to generate a second noise-suppressed audio frame. The one or more processors are further configured to execute the instructions to provide the noise-suppressed audio frames to an attention-pooling network. The attention-pooling network is configured to generate an output noise-suppressed audio frame.
