Abstract
A sound processing system operative to measure the level of diffusivity of the sounds present in the input sound signal. The system includes a plurality of input channels for receiving audio signals from an audio scene, the audio scene comprising at least one target sound in the presence of background noise. A diffusivity measurement unit is included so as to be operably coupled to the plurality of input channels to receive the audio signals therefrom and measure a level of diffusivity of the sounds present therein. A leveler unit is operably coupled to the plurality of input channels for receiving the audio signals therefrom and for applying a gain to the audio signals to minimize variations in the audio signal levels. A controller is operably coupled to the diffusivity measurement unit and the leveler unit to control the gain applied to the audio signals by the leveler unit based on the level of diffusivity of the sounds present therein.
