The method includes determining a super-directional differential beamforming weighting coefficient, acquiring an audio input signal and determining a current application scenario and an audio output signal, acquiring, a weighting coefficient corresponding to the current application scenario, performing super-directional differential beamforming processing on the audio input signal using the acquired weighting coefficient in order to obtain a super-directional differential beamforming signal in the current application scenario, and performing processing on the formed signal to obtain a final audio signal required by the current application scenario. By using this method, a requirement that different application scenarios require different audio signal processing manners can be met."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio signal processing method and apparatus and differential beamforming method and apparatus","description":"An audio signal processing method and apparatus and a differential beamforming method and apparatus to resolve a problem that an existing audio signal processing system cannot process audio signals in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641929","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
