Abstract
Example embodiments provide a process that includes one or more of receiving an audio signal at a feedback compressor circuit, multiplying the received audio signal with a power feedback signal to create a product audio signal, wherein the feedback signal comprises a low-pass filtered signal, applying a power amplifier to the product audio signal, and providing the amplified product audio signal as an output signal to a speaker.
Claims20
A method comprising:
- multiplying an audio signal and a power feedback signal to create a product audio signal;
- responsive to an output signal power exceeding a threshold value, subtracting the excess of of the threshold value from the audio signal;
- and
- amplifying the product audio signal as the output signal to a speaker.

An apparatus comprising:
- a processor configured to
- multiply an audio signal and a power feedback signal to create a product audio signal;
- responsive to an output signal power exceeding a threshold value, subtract the excess of the threshold value from the audio signal;
- and
- amplify the product audio signal as the output signal to a speaker.
