The apparatus furthermore has a loudness estimator for estimating a first loudness measure using the filtered direct signal and for estimating a second loudness measure using the filtered reverberation signal or the filtered mix signal, where the filtered mix signal is derived from a superposition of the direct signal component and the reverberation signal component. The apparatus furthermore has a combiner for combining the first and the second loudness measures to obtain a measure for the perceived level of reverberation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for determining a measure for a perceived level of reverberation, audio processor and method for processing a signal","description":"An apparatus for determining a measure for a perceived level of reverberation in a mix signal consisting of a direct signal component and a reverberation signal component, has a loudness model process","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9672806","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.
