Abstract: Interchannel coherence is one of the key features of stereo and multichannel audio that contribute to the perception of width. Certain production techniques, most commonly those using linear coincident microphones, are characterized by excessively high interchannel coherence. Addressing this issue, the authors propose a blind spatial sound enhancement technique that adjusts the coherence in frequency bands while minimizing the change of timbre. The adaptive processing uses regularized least squares optimized mixing, decorrelation, and bypassed onsets. Results of listening experiments show significant improvements by the processing to the attributes width, preference, and overall sound quality without observing adverse effects.

AB - Interchannel coherence is one of the key features of stereo and multichannel audio that contribute to the perception of width. Certain production techniques, most commonly those using linear coincident microphones, are characterized by excessively high interchannel coherence. Addressing this issue, the authors propose a blind spatial sound enhancement technique that adjusts the coherence in frequency bands while minimizing the change of timbre. The adaptive processing uses regularized least squares optimized mixing, decorrelation, and bypassed onsets. Results of listening experiments show significant improvements by the processing to the attributes width, preference, and overall sound quality without observing adverse effects.
