Announcement: Audio TK 2.1.0

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.

Audio ToolKit: Mailing list for beta testers

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…

Announcement: ATKGuitarPreamp 1.0.0

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.

Analog modeling: Comparing preamps

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.

Using Audio ToolKit with JUCE 5

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.

Announcement: ATKStereoUniversalDelay 1.0.0

I’m happy to announce the release of a stereo delay that allows ping-pong like effects based on the Audio Toolkit. They are available on Windows and OS X (min. 10.11) in different formats.

Announcement: Audio TK 2.0.0

ATK is updated to 2.0.0 with a major refactoring to ensure signed/unsigned consistency, new Adaptive module and EQ design. Complex-valued filters are also now available to allow simultaneous dual channel processes and advanced filters like complex LMS filters.

Audio Toolkit: Create a FIR Filter from a Template (EQ module)

Last week, I published a post on adaptive filtering. It was long overdue, but I actually had one other project on hold for even longer: allowing a user to specify a filter template and let Audio Toolkit figure out a FIR filter from this template.
