Abstract
A mixing system provides both clipping protection and signal level conservation while the system operates in the original width type. The mixing system includes a first input multiplier multiplying a first digital input signal by a first gain value to provide a first scaled signal, a second input multiplier multiplying a second digital input signal by the first gain value to provide a second scaled signal, a combiner combining the first scaled signal and the second scaled signal to provide a combined signal, a soft limiter soft limiting the combined signal by reducing some of the amplitudes of the combined signal to provide a soft limited signal, and an output multiplier multiplying the soft limited signal by a second gain value to provide a mixed output signal, wherein the first gain value is a value that is equal to an inverse value of the second gain value.
