文摘

Sound separation problems are geometrically studied in a novel way. A new mixing matrix estimation method is introduced. A theoretical relationship between time and level differences is determined. Only time differences must be estimated, avoiding the calculation of the level ones. Time differences are obtained with a classical algorithm robust to reverberation.
