Download Spectrograph Software for Computer Voice Analysis

By Jeremy Fisher

There is a wide selection of voice analysis software available on the web that can be used to produce spectrograms. They have a range of features and most are available for free trial. Here is an overview of some of the software packages I’ve tried.


Drew University Music Department LAS3 Lab.
A free version of this software, called ‘VoceVista – RealTime’ is available for download from the Vocalist web site. It’s a good program to start with if you’re learning about computer voice analysis and only takes a few minutes to download. The free version is limited to recording a maximum of eight seconds but does allow you to save examples. The fully featured version costs around $65. The Drew University Music Department has a web site with articles describing VoceVista’s use in the vocal studio (link below).
More information on the software is available from the VoceVista web site:http://www.vocevista.com/
