In the last blog post, we saw the individual effect of each stage of the Boss MT2 pedal. But with all these effects impacting each other, what is the final find of spectrum that we get?
Category: Digital filters
In the previous entry in this series, we saw the effect of the gyrator in a circuit. Now we can analyse each stage individually.
I’m happy to announce the release of ATK MTB based on the Audio Toolkit and JUCE. It is available on Windows (VST3) and macOS (min. 10.11, x86_64 and ARM64) in different formats.
MTB is a variation of the MT2 plugin geared towards the bass. The cut frequencies for the different filters are lowered to match the bass frequencies better. As such, MTB spills less in high frequencies than MT2. Not that MT2 cannot be used for the bass if that’s the sound you are looking for!
This plugin requires the universal runtime on Windows, which is automatically deployed with Windows update (see this discussion on the JUCE forum). If you don’t have it installed, please check Microsoft website.

This mono plugin emulates the full pedal up to the non-linear post tone shaping circuit and uses standard SVF filters for the tone controls and allows for finer Q tuning as hidden parameters. More information on how the pedal and the plugin work is available on this page.

After a long pause, I’m pleased to announce the release of Audio ToolKit 3.3.0.
After a long pause, let’s go on on our MT2 discovery trip. Last time, we analyzed the perfect gyrator that is sometimes used to replace coils.
As 2021 begins, there are a few changes in how AudioToolKit will grow in the future.
The first important point is that all repositories will now be on a dedicated space on GitHub. The reason is that there are many projects on my own page and Audio ToolKit was basically hidden there.
There was also a unique repository with all plugins that I designed, and it started to be very messy, with some projects that don’t even build anymore. One of the objectives of 2021 will to create a dedicated repository for these plugins and release them again, with JUCE 6 and Audio ToolKit 3.2.
Another project that I have been working on is ATK Modelling. I already presented some work on it at ADC18, but I decided now to make the project public. It’s the project I have worked the most in the past few months, and it is now at a stage where we can model lots of pedals. So on top of new articles on ATK Modelling, there is going to be more on the MT2 pedal, a series I started before the pandemic, and hopefully a release of a full guitar version as well as an adaptation for bass.
As I’m rewriting the plugins, I’m also thinking about their GUI, and if you have ideas for better UIs, please let me know, I would gladly use outside help to create nice and usable ones.
It’s a question I always asked myself. Models in SPICE are usually for full models, or you can use a gain voltage gain as well. What are the implications of selecting one model over another for a real time model? Let’s go for the more complex model to the simplest ones.
Audio ToolKit is finally updated to 3.2.0. The main changes for this release are mainly cleanup of the API and better C++17 support with variable defaulting.
In almost all analog modeling algorithms, we solve a (non-)linear system they require at some point to solve
