摘要: A signal processing apparatus includes: a learning unit that finds separating matrix for mixed signals in which outputs from plurality of sound sources are mixed, by process applies ICA (Independent Component Analysis) to observed including the signals; separation separate and generate separated corresponding each sources; source direction estimating computes generated signals. The calculates cross-covariance matrices between time segments time-frequency domain, phase differences elements matrices, applying computed differences.
