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. Simply playing the sound at a different rate is not a solution. The frequencies would be distorted in proportion
