System and method for dynamically mixing audio signals
A system and method for dynamically mixing audio signals may calculate a signal amplitude for each of two or more audio signals. The signal amplitude may be the absolute value of the audio signal. A signal sum may be calculated using each of the two or more signal amplitudes. Each of the two or more...

| description | A system and method for dynamically mixing audio signals may calculate a signal amplitude for each of two or more audio signals. The signal amplitude may be the absolute value of the audio signal. A signal sum may be calculated using each of the two or more signal amplitudes. Each of the two or more signal amplitudes may be smoothed. The signal sum may be smoothed. The smoothing may be a filter or a leaky integrator. A respective mixing gain may be calculated for each of the two or more audio signals using a respective ratio of each of the two or more smoothed signal amplitudes and the smoothed signal sum. Each of the two or more audio signals may be gain adjusted responsive to the respective mixing gain. Each of the two or more gain adjusted audio signals may be mixed to create an output signal. |
