Abstract
An ultrasonic emitter system includes a digital processing system for adjusting the amplitude of an ultrasonic carrier signal to increase audio levels of an audio signal during lower power portions of the audio signal. To increase the audio levels without introducing unwanted audio and/or distortion, an additive constant is added to the ultrasonic carrier signal based on a rolling average audio signal power measurement.
