Abstract
A source width estimation system may estimate an auditory source width of a sound. The system detects a first frequency modulated noise signal and a second frequency modulated noise signal. The detected noise signals may be processed to obtain an average value of a lateral width of a binaural activity over time and a plurality of sub-bands. The auditory source width of the noise signals may be determined from the average value of the lateral width of the binaural activity.
