Book review: The Audio Effects Workshop

How to explain the different kind of audio effects and how to understand what their use is? Although I learnt a lot by practice, there is sometimes the need for some theory and for experiments. I tried to find a book that matches these two points: good theory and proper practice. I’ve chosen this book, with tracks on a CD for experimentation. Was it really what I was looking for?

Book review: SONAR X1 Power!: The Comprehensive Guide

I think I’ve said it already, I have a rock band. Currently, we are recording our first album, and while we used Traktion in the past, I’m considering moving to Sonar (it is continuously updated and has a great reputation, also I’ve played a few time in the past with its ancestor Cakewalk).

So let’s talk about the book’s comprehensive guide.

Announcement: QtSimpleEQ 1.0 (QtVST)

I’m pleased to announce the 1.0 version of QtSimpleEQ, a plugin with one low-pass, two peak and one high pass second-order filters. Nothing fancy in the algorithms, it’s mainly another show case for Qt VST plugins.

The code is available under the GPL2 on github and on Sourceforge.

The plugin can be download on the Sourceforge project page.

The plugin was tested with Tracktion 3 (Windows XP).

QtVST, Qt and QtSimpleEQ

Today, I wanted to announce my new plugin, a 4-bands EQ, but when I started a test with pyVST, I encountered strange things:

  • The first is my fault, as the code of the EQ disappeared from my Git repository, so I have to code it again. Mainly it is just plugin the correct actions between the filters and the GUI.
  • The second is an error at the end of the test. I’ve updated my Qt version from 4.7.1 to 4.7.4, and since this update (or perhaps since I updated to Python 2.7 for pyVST), I found that even a recompiled QtSimpleOverdrive has the same behavior. It did not when I released it. It seems that Qt is complaining about events that are bounced between different threads, but the actual error message is more cryptic, and impossible to debug the application at this point.

I hope to fix these mistakes this month, I really hope I can get QtVST to work again.

Announcement: QtSimpleOverdrive 1.2 (QtVST)

I’m pleased to announce the 1.2 version of QtSimpleOverdrive.

Since last version, the GUI was changed, and mainly the automation has been fixed. As such, old parameters are no longer valid, sorry…

The code is now available under the GPL2 on github and on Sourceforge.

The plugin can be download on the Sourceforge project page.

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: https://sourceforge.net/projects/qtvst/files/QtSimpleOverdrive/

If you find any issue, please submit it on Github: https://github.com/mbrucher/qtvst

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 (https://github.com/mbrucher/QtVST), 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.

The download page: https://sourceforge.net/projects/qtvst/files/

Book review: Music Theory for Computer Musicians

Book review: Composition for Computer Musicians

My biggest hobby remains music. As a former trumpet player, current drummer and bass player, I spent a lot of time studying solfege, and a little bit of composition. Besides this, I’ve mixed an album for one of my former bands, mastered some tracks for others (and my current one), so I’m also a computer musician. This is why this book from Michael Hewitt was of high interest to me.
