Abstract
An audio amplifier clipping avoidance apparatus (140) identifies signal segments of an audio signal that can have an amplitude peak greater than a particular amplifier clip avoidance threshold (530). A scaling factor is determined for each signal segment based on the particular threshold (540). Signal segments are scaled with corresponding scaling factors to produce a modified audio signal having no signal segments with an amplitude peak greater than the particular threshold (560).
