A method of recording ambisonic sound fields with a spatially distributed plurality of ambisonic microphones comprising a step of recording sound signals from plurality of ambisonic microphones a step of converting recorded sound signals to ambisonic sound fields and a step of interpolation of the ambisonic sound fields according to the invention comprises a step of generating synchronizing signals for particular ambisonic microphones for synchronized recording of sound signals from plurality of ambisonic microphones and during the step of interpolation of the ambisonic sound fields it includes filtering sound signals from particular microphones with individual filters having a distance-dependent impulse response having a cut-off frequency fc(dm) depending on distance dm between point of interpolation and m-th microphone applying gradual distance dependent attenuation applying re-balancing with amplification of 0th ordered ambisonic component and attenuating remaining ambisonic components. Invention further concerns recording system and computer program product.
A method of recording and interpolation of ambisonic sound field with a spatially distributed plurality of ambisonic microphones comprising a step of recording sound signals from the plurality of ambisonic microphones, a step of converting recorded sound signals to an ambisonic sound fields, and a step of interpolation of the ambisonic sound fields, the step of recording further comprises a step of generating synchronizing signals for particular ambisonic microphones of the plurality of ambisonic microphones for synchronized recording of sound signals from the plurality of ambisonic microphones and the step of interpolation of the ambisonic sound fields includes:
A computer program product stored in a non-transitory computer readable medium and for recording and interpolation of ambisonic sound fields, which when executed on a processing device fed with sound signals recorded from a plurality of ambisonic microphones, is adapted to cause the processing device to execute conversion of the sound signals to ambisonic sound fields and interpolation of said ambisonic sound fields, characterized in that the interpolation includes:
