“…In this respect, wind noise can cause severe degradations in terms of desired sound quality by inducing highly non-stationary distortions at low frequencies. In [1], the authors proposed to reduce wind noise in multi-channel recordings by employing a parametric multi-channel Wiener filter (PMWF) [2]. The adaptive trade-off between signal distortion and noise reduction was computed based on the ratio of the difference-signal and sum-signal power of the input, referred to as power ratio in the following.…”

Noise reduction in B-format recordings is particularly challenging as it concurrently requires to suppress undesired signals and preserve the spatial properties of the acoustic environment. In particular, wind noise poses an undesirable acoustic condition outdoors. In this work, methods to reduce wind noise while limiting the spatial distortions of the original signal are proposed based on recent works of the present authors. The main contributions are the derivation of the mentioned methods for B-format signals and the usage of the dipole-to-omnidirectional power ratio to control the trade-off between the desired-signal distortion and the noise reduction. The proposed methods are evaluated using B-format wind-noise recordings.
