... to have a frequency invariant gain over all angles. This might not be necessary and if a gain constraint is confined to a specific angle, then the FI performance over that selected region (in frequency ... well as reduced number of microphones employed. The objective function is designed to minimize the overall spatial response of the beamformer with a constraint on the gain being smaller t...
