ABSTRACT:
An audio signal processing system and method is disclosed. In a particular embodiment, the audio signal processing system includes a first electrical path responsive to a power supply of an audio amplifier. The first electrical path can include a low pass filter to filter a direct current (DC) component of the power supply and a first analog-to-digital converter (ADC) responsive to the low pass filter. The audio signal processing system also includes a second electrical path responsive to the power supply. The second electrical path can include a high pass filter to filter an alternating current (AC) component of the power supply and a second ADC responsive to an output of the high pass filter. The audio signal processing system includes compensation logic to modify an audio signal based on a first signal generated from the first electrical path and a second signal generated from the second electrical path.
