Abstract
A method for modeling the microphone characteristics of a target microphone is provided. The impulse response of the target microphone is measured over various angles. Signal conditioning of the measurement data is performed. The spatial response is adjusted based on a spatial response adaptation algorithm, and filter parameters and / or model parameters are determined.
