Abstract: A computer-implemented method can include receiving a first signal corresponding to a first flow of acoustic energy, applying a transform to the received first signal using at least a first amplitude-independent window size at a first frequency and a second amplitude-independent window size at a second frequency, the second amplitude-independent window size improving a temporal response at the second frequency, wherein the second frequency is subject to amplitude reduction due to a resonance phenomenon associated with the first frequency, and storing a first encoded signal, the first encoded signal based on applying the transform to the received first signal.

Abstract: A method including receiving an audio signal, generating a transformed audio signal by transforming the audio signal using a plurality of windows each separated in time, generating an interpolated audio signal by interpolating the transformed audio signal, generating a separated audio signal by applying a mask to the interpolated audio signal, and compressing the separated audio signal.

Abstract: A method including receiving a plurality of audio channels based on an audio stream, applying a model based on at least one acoustic perception algorithm to the plurality of audio channels to generate a first modelled audio stream, quantizing the plurality of audio channels using a first set of quantization parameters, dequantizing the quantized plurality of audio channels using the first set of quantization parameters, applying the model based on at least one acoustic perception algorithm to the dequantized plurality of audio channels to generate a second modelled audio stream, comparing the first modelled audio stream and the second modelled audio stream, in response to determining the comparison of the first modelled audio stream and the second modelled audio stream does not meet a criterion, generating a second set of quantization parameters, and quantizing the plurality of audio channels using the second set of quantization parameters.

Abstract: Implementations set forth herein relate to an automated assistant that can control a sequence of operations for a routine according to whether power data indicates that energy expense and/or energy consumption can be preserved by modifying the sequence of operations for the routine. In some implementations, the automated assistant can suggest certain routines, and/or triggering conditions for operations of the routine, to reduce energy expense and/or energy consumption. Alternatively, or additionally, the automated assistant can infer certain operation requests or triggering conditions depending on whether the user has expressed an interest in preserving energy resources and expenses. In this way, the automated assistant can facilitate minimizing energy consumption and/or energy expenses without necessitating that the user exclusively, or manually, schedule all assistant operations with particularity.

Abstract: Spatial audio may be generated by a speaker array that is switched according to rows and/or columns to reduce its cost and complexity. The speaker array may include a row of speakers that are each coupled to a different column channel. The rows of speakers can receive portions of the spatial audio on a row-by-row basis as each row is activated to couple the speakers in a row to their respective column. This switched approach reduces a number of required audio sources. The audio sources may generate PWM signals for each column using an approach that is similar to that found in Class-D amplification or sigma-delta Modulation. Analog signals may be recovered from the PWM signals using a low-pass filter positioned before each speaker in the array.
