Patent attributes
A method for powering an audio amplifier includes receiving an input audio signal in an audio signal processor, delaying the input audio signal in the audio signal processor to generate a delayed audio signal, predicting a power demand estimate by analyzing the input audio signal to calculate the power demand estimate in the audio signal processer, and selecting, by the audio signal processor, power conversion settings for a DC to DC converter on the basis of the power demand estimate. The method further includes supplying power input to the DC to DC converter, converting the power input in accordance with the power conversion settings to provide a power output, powering the audio amplifier using the power output, and supplying the delayed audio signal to the audio amplifier from the audio signal processor to generate an amplified audio signal.
