Announcement: QtSimpleOverdrive 1.0 (QtVST)

I’m pleased to announce the release of my first VST plugin (Windows 32bits), based on the simple overdrive prototype.

It is a mono filter, with an oversampling of 2 to 32, based on polyphase filters, and the undersampling is done after an 8th order Butterworth lowpass filter with a cut frequency of 22kHz.

The source code will be available (under the GPL) in the future if there is interest in the plugin and its support. The exact way it works will be explained in a future blog post.

The audio plugin is available on Sourceforge:

If you find any issue, please submit it on Github:

Please note that the oversampling can be quite CPU intensive (on my laptop, an Intel Core2 T7200, using an oversampling of 4 at 96kHz uses the full power of one core).

A Sourceforge project for QtVST

I’ve set up a SourceForge project where I will put all the binaries for this project.

The source code is still on Github (, but it won’t always contain the source code for each VST plugin. The next plugin I’m working on is based on the overdrive I’ve blogged about some months ago.
