This paper presents a novel technique for time-scale modification (TSM) which integrates time-domain and frequency-domain processing. The method relies on frame-by-frame classification to choose between different techniques adapted to different signal types. Provisions are taken to seamlessly switch between techniques. The result is a more universal TSM algorithm that yields continuous high quality results on a wider range of audio signals. The method is tested on mixed-content signals and formal listening tests results are discussed.
