In the context of audio signals, techniques are provided to allow a user to “time stretch” an audio signal file to change the duration of the stretched portion of the audio. The user may select how the change affects the total duration of the audio signal. Options are provided for “shifting” the non-selected portion of the signal, or for not shifting the non-selected portion of the signal. When the non-selected portion is not shifted, the signal editing tool automatically generates audio for the gap (for shrinking operations), and automatically deletes audio that overlaps with the stretched portion (for stretching operations)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stretching/shrinking selected portions of a signal","description":"Techniques are described to allow a user of a signal editing tool to “stretch” or “shrink” a selected portion of a recorded signal to change the length of the selected portion of the signal relative t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538761","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.
