In doing so, the multiband ducker separates the music signal into different frequency ranges, which may include low, middle, and high-range frequencies. The multiband ducker then reduces the amplitude of the specific range of frequencies found in the speech signal, typically the mid-range frequencies. When the ducked music signal and the speech signal are combined, the resultant signal includes important frequencies of the original music signal, including low-range and high-range, thereby allowing perception of the music signal to continue in relatively uninterrupted fashion. Additionally, the combined signal also includes the speech signal, allowing for the perception of intelligible speech concordant with the perception of music."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiband ducker","description":"A multiband ducker is configured to duck a specific range of frequencies within a music signal in proportion to a corresponding range of frequencies within a speech signal, and then combine the ducked","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813039","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.
