Abstract. The independent control over the time evolution and the pitch contour of audio signals has always stood very high on the wish-list of the audio community because it breaks the traditional tie between pitch and rate of playback. Rudimentary solutions to that problem date back to the analog days, but the recent advent of fast digital audio processors has made it …

3. TIME AND PITCH SCALING The time and pitch scaling algorithms are used to change the speech rate without affecting the pitch or timbre of the speaker voice, or vice-versa – to change the pitch while leaving the rate and the timbre unaffected. The mathematical descriptions of the terms are given in this section. 3.1. Time Scaling

A method for independently modifying the time and pitch scale of acoustic signals, with an emphasis on speech signals is proposed in this paper. The algorithm developed here is based on Short Time Fourier Transform(STFT). The purpose of this paper is to devise a way to change the rate of a pre-recorded sound without altering the frequency content.

Original Sound. (WAVE, 106k) Pitch Shifted Sound. (WAVE, 106k) Frequency Shifted Sound. (WAVE, 106k) 1.2 Time Compression/Expansion. Time Compression/Expansion, also known as “Time Stretching” is the reciprocal process to Pitch Shifting. It leaves the pitch of the signal intact while changing its speed (tempo).

1.1 Time-Scale Modification of Audio Signals Sound is a phenomenon that lives in manifold dimensions. Besides pitch, volume, timbre and many others, the time is an essential component of audio signals. Being able not only to analyze but also to modify aspects of sound is an important issue in the field of audio signal processing.
