Signal Processing Application - Pitch Shifting in Real Time

VERSION 3

Created on: Jun 15, 2009 2:08 AM by Macpac - Last Modified:  Jun 15, 2009 3:19 AM by Macpac

Functional Description

This example uses online Gabor transform and online Gabor expansion to shift the pitch of a speaker in real time. This application can be used to disguise a speaker's gender, to correct instruments' frequency and to make unperceptive sounds audible. You can customize this example according to your own needs.

 

Caveats and Additional Notes

The attached zip file contains the executable of the demo and its source code. To run the executable, you need the LabVIEW Runtime Engine 8.6.1. You can download a free copy of this software from http://joule.ni.com/nidu/cds/view/p/id/1244/lang/en. I would appreciate it if you rank it and give some comments. Your feedbacks will help us to share better examples in the future.
