We developed a small dodecahedral microphone array device and propose a sound source separation method based on frequency-domain independent component analysis with the developed device. The developed device's diameter is 8 cm and the intervals among each face are 36 •. Microphones can be installed on ten faces except the top and bottom faces, and 16 holes(More)
A sound source separation method based on frequency-domain independent component analysis (FD-ICA) is proposed. This method fully utilizes the dodecahedral microphone array (DHMA), which has several merits: 1) the size of the array is very small and thus easy to handle; 2) the amplitude difference among microphones on the different surfaces is large; and 3)(More)
