Audio Toolkit: ATK SD1 Implementation

I just released my SD1 simulation, and now it is time to explain why is inside this plugin. Not everything in the original pedal was simulated, and different schemes were used to tackle the different stages.

Announcement: Audio TK 0.2.0

It’s time for a new release of the toolkit. Much has been done in terms of basic filters, but also to simplify usage (static and shared libraries are compiled, no need to reset the pipeline before calling process…).

Audio Toolkit: Optimization of the overdrive simulation

I’ve explained in earlier posts how to simulate a simple overdrive circuit. I’ve also explained how I implemented this in QtVST (and yes, I should have added labels on those images!), which was more or less the predecessor of Audio TK.

The main problem with simulating non linear circuits is that it costs a lot. Let’s see if I can improve the timings a little bit.

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.

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).
