Transform ambisonic coefficients using an adaptive network

A device comprising:

• a memory configured to store untransformed ambisonic coefficients at different time segments;
• and
• one or more processors configured to:
• convert microphone signals output captured at different microphone positions of a non-ideal microphone array into the untransformed ambisonic coefficients based on performing a directivity adjustment;
• obtain the untransformed ambisonic coefficients at the different time segments, where the untransformed ambisonic coefficients at the different time segments represent a soundfield at the different time segments;
• and
• apply one adaptive network, based on a constraint, to the untransformed ambisonic coefficients at the different time segments to generate transformed ambisonic coefficients at the different time segments, wherein the transformed ambisonic coefficients at the different time segments represent a modified soundfield at the different time segments, that was modified based on the constraint.
