Abstract
A system for wind noise suppression is disclosed. The system comprising a first and a second primary microphone configured to generate a first and a second primary electric signal indicative of a first and second primary audio signal, respectively. The system further comprises a secondary detector configured to generate a first secondary electric signal indicative of a secondary audio signal. The system comprises a signal processor comprising a wind strength module configured to determine a wind strength, based on the first primary electric signal and the second primary electric signal, a wind noise module configured to determine a noise estimate, based on the wind strength, and a noise reduction module configured to process the first secondary electric signal to generate a noise-suppressed secondary signal, based on the determined noise estimate.
