  • code that is executable to process an audio signal in an audio amplifier;

    code that is executable to determine an actual voltage of a rail of an audio amplifier power supply;

    code that is executable to compare the actual voltage of the rail of the audio amplifier to a reference;

    code that is executable to adjust a compressor knee of a compressor lower in response to the actual voltage being less than the reference, the compressor being included in the audio amplifier and the audio signal provided as an input to the compressor; and

    code executable to adjust the compressor knee of the compressor higher in response to the actual voltage being greater than the reference.
