Abstract
A method comprising: at an electronic device () having an array microphones () with a plurality of microphones and a processor (): receiving a plurality of microphone signals (x, x, x) from the plurality of microphones; generating a processed signal (XP) from the plurality of microphone signals using one or both of beamforming and deconvolution; generating a compensated processed signal (XO) by compensating the processed audio signal (XP) in accordance with compensation coefficients (Z). Generating the compensated processed signal comprises: generating first spectrum values (PXP) from the processed audio signal; generating reference spectrum values (<PX>) from multiple second spectrum values (PX, PX, PX) generated from each of at least two of the microphone signals in the plurality of microphone signals (x, x, x); and generating the compensation coefficients (Z) from the reference spectrum values (<PX>) and the first spectrum values (PXP). The compensation may improve undesired effects related to e.g. coloration at the output of multi-microphone systems involving e.g. one or both of beamforming and deconvolution of microphone signals from a microphone array.
