audio signal processing using matlab




In Time-Scaled Audio Signal, nowadays, it has become in one of The most powerful tools, not only in the Telecommunications field but in the music software production, whence “The Time-Scaled Modification”, TSM by its acronym, this is a essential tool. This paper is a guide for the application of the WSOLA (Waveform Similarity Overlap and Add), method. This method is developed in MATLAB software where it accelerates or slow a audio file by a factor called “Alpha” that is in the range of 0.33 to 4. This has as objective to foster a better understanding of this great technique for all the procedures of the time scaling
