The audio encoder is configured to selectively include bandwidth extension information into the encoded audio information in a signal-adaptive manner. An audio decoder has a low frequency decoder which decodes an encoded representation of a low frequency portion to obtain a decoded representation of the low frequency portion, and a bandwidth extension which obtains a bandwidth extension signal using a blind bandwidth extension for portions of an audio content for which no bandwidth extension parameters are included in the encoded audio information, and which obtains the bandwidth extension signal using a parameter-guided bandwidth extension for portions of the audio content for which bandwidth extension parameters are included in the encoded audio information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio encoder, audio decoder, method for providing an encoded audio information, method for providing a decoded audio information, computer program and encoded representation using a signal-adaptive bandwidth extension","description":"An audio encoder has a low frequency encoder which encodes a low frequency portion of the input audio information to obtain an encoded representation of the low frequency portion, and a bandwidth exte","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9646624","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.
