Patent ID: 8428277

Claim:
A mixing system comprising: a first input multiplier multiplying a first digital input signal by a first gain value to provide a first scaled signal, wherein the first digital input signal is derived from an audio signal, wherein the first digital input signal is of a fixed width data type having a fixed length of x bit integers and wherein the first scaled signal is of the fixed width data type having the fixed length of x bit integers; a second input multiplier multiplying a second digital input signal by the first gain value to provide a second scaled signal, wherein the second digital input signal is of the fixed width data type having the fixed length of x bit integers and wherein the second scaled signal is of the fixed width data type having the fixed length of x bit integers; a combiner combining the first scaled signal and the second scaled signal to provide a combined signal, wherein the combiner is combining the first scaled signal and the second scaled signal at a fixed length of y bit integers and wherein the combined signal outputted from the combiner is of the fixed width data type having the fixed length of x bit integers; a soft limiter soft limiting the combined signal by reducing some of the amplitudes of the combined signal to provide a soft limited signal, wherein the soft limiter is soft limiting the combined signal at the fixed length of x bit integers; and an output multiplier multiplying the soft limited signal by a second gain value to provide a mixed output signal, wherein the mixed output signal is of the fixed width data type having the fixed length of x bit integers, wherein the first gain value is a value that is equal to an inverse value of the second gain value, and wherein the value of y is greater than the value of x and wherein one of either the first input multiplier, the second multiplier, the combiner, the soft limiter, or the output multiplier is a processor.
