Pitch Shifting Using The Fourier Transform

Posted by Bernsee on September 21, 1999 in Tutorials

With the increasing speed of todays desktop computer systems, a growing number of computationally intense tasks such as computing the Fourier transform of a sampled audio signal have become available to a broad base of users. Being a process traditionally implemented on dedicated DSP systems or rather powerful computers only available to a limited number […]

The DFT “à Pied”: Mastering The Fourier Transform in One Day

Posted by Bernsee on September 21, 1999 in Tutorials

If you’re into signal processing, you will no doubt say that the headline is a very tall claim. I would second this. Of course you can’t learn all the bells and whistles of the Fourier transform in one day without practising and repeating and eventually delving into the maths. However, this online course will provide […]

Time Stretching And Pitch Shifting of Audio Signals - An Overview

Posted by Bernsee on August 18, 1999 in Tutorials

1. Introduction - Pitch Shifting
As opposed to the process of pitch transposition achieved using a simple sample rate conversion, Pitch Shifting is a way to change the pitch of a signal without changing its length. In practical applications, this is usually achieved by changing the length of a sound using one of the below methods […]
