Abstract :
A new method is described for high-quality time or pitch modifications of audio signals. The method is a simple but efficient improvement of the splice method. Thanks to its simplicity, the algorithm can be implemented to run in real-time on standard microprocessors. Informal listening tests have demonstrated the method´s capability to modify high-quality audio signals without introducing audible artifacts for moderate modification factors (up to 15%)
