Abstract (en)
[origin: EP2362681A1] The method involves calculating a spectral filter function (540) based on current, frequency-dependent phase difference vector and respective calibration-position-specific, frequency-dependent phase difference vector of a selected calibration position. A signal spectrum of a signal is generated by multiplication of frequency spectra of current microphone signals with the spectral filter function of the respective selected calibration position (550). The signal is obtained (560) for the respective selected calibration position by inverse transformation of the generated signal spectrum. Independent claims are also included for the following: (1) a device for phase-sensitive processing of sound signals of a sound source, comprising two microphones (2) a computer program product comprising a set of instructions for phase-sensitive processing of sound signals of a sound source.
