In release 2.2.0, ATK gained new EQ filters that are vectorized. These filters cannot be used to filter different bands from the same input signal (yet), but they can be used to filter in the same way several channels.
ATK is updated to 2.2.0 with the major introduction of vectorized filters. This means that some filters (EQ for now) can use vectorization for maximum performance. More filters will be introduced later as well as the Python support. Vector lanes of size 4 and 8 are supported as well as instruction sets from SSE2 to AVX512.
This is also the first major release that officially supports the JUCE framework. This means that ATK can be added as modules (directly source code without requiring any binaries) in the Projucer. The caveat is that SIMD filters are not available in this configuration due to the requirement for CMake support to build the SIMD filters.

As some may know, I’ve switched from wdl-ol to JUCE 5 for my free plugins. In the past, I had to modify by hand all the projects created by the Projucer. And each time JUCE is updated, I need to add these changes to the generated project.
On the develop branch, and in the next minor release ATK 2.1.2, modules for the Projucer will be available. This will enable an easier integration of ATK in your project, as you will “just” need to add these modules to the Projucer (and some additional include files to make ATK compliant with JUCE hierarchy).
There are currently 11 new modules (shameless comparison, that’s far more than the new DSP module, even if there are some filters than I’m missing, but feel free to propose a pull request with new features!).
See the explanation on the release branch and let me know what you think: https://github.com/mbrucher/AudioTK/tree/develop/modules/JUCE
ATK is updated to 2.1.0 with a major refactoring of the Python wrappers and extensive testing of them. New filters were also added to support more complex pipelines (mute/solo and circular buffers for real-time spectrum displays) and Audio ToolKit provies now a CMake configuration file for easier integration in CMake projects.

Vinyl has become trendy again, and as such, I’ve been asked to add some new filters in Audio ToolKit. Here is a small dive in RIAA land.
Recently, I’ve struggled with releasing perfect plugins. There were some glitches in the last 2 plugins that could have been avoided easily with more testing.
So this is a call for people who are interested in my plugins. You can join the mailing list, share your ideas of the current plugins, and the future ones, about what can be made better, how it can be better…
I’m happy to announce the release of a modeling of the Vox AC30 preamplifier stage followed by a JCM800 tone stack based on the Audio Toolkit. They are available on Windows and OS X (min. 10.9) in different formats.
I’m happy to announce the release of a modeling of the Fender Bassman preamplifier stage based on the Audio Toolkit. They are available on Windows and OS X (min. 10.9) in different formats.
In a previous post, I explained how I modeled the triode inverter circuit. I’ve decided to put it inside two different plugins, so I’d like to present in 4 pictures their differences.
As some may have seen online, ROLI released a new version of JUCE. The nice thing is that they added a new tier for people like me who don’t sell plugins but who don’t want to release their code under the GPL license for diverse reasons (for me, it was formerly incompatibility between VST3 license and the GPL).
With JUCE 5, you have support for all major APIS, from VST2 to Audio Unit v3 and also AAX or VST3. And you can develop your own plugins. The caveat with this tier is that you have a splash screen and a tracking of your users… (actually, there is a flag to remove both). the advantage is that on MacOS, there is no more SDK conflicts, and I have Audio Unit 3 support
So I’ve started playing with Projucer and built a barebone ATK plugin that doesn’t do anything. What I can say is that the worst part is handling universal binaries, support 32bits plugins, as the JUCE project builder overwrites all my changes. Even adding ATK is painful with the project manager.
So instead, I’m going the WDL-OL here, and keeping this ATKJUCE plugin as the simple plugin I’ll duplicate by changing the names and its content. I have my builders that build the plugins and creates the installers, all that while keeping the same JUCE core code (it is shared by all plugins).
The next step is trying to make sense of the API to build a nicer GUI than what I currently have (probably something flat). Indeed, the tutorials on the GUI are small and too basic, but WDL-OL was no better in that aspect, but with more examples.
