Abstract:
1. A method, comprising: detecting a first frequency modulated noise signal and a second frequency modulated noise signal; filtering the detected noise signals to obtain sub-band signals for a plurality of sub-bands; determining a binaural activity over time and a lateral width for each of the plurality of sub-bands; determining an average value of the lateral width of the binaural activity over time and the plurality of sub-bands; determining an auditory source width of the noise signals based on the average value of the lateral width of the binaural activity; and cutting the binaural activity at one or more edges by applying a cutting function with an adaptive threshold, and where the act of determining the auditory source width comprises determining the auditory source width of the noise signals based on the edge-cut binaural activity.
