ATK is updated to 3.1.0 with heavy code refactoring. Old C++ standards are now dropped and it requires now a full C++17 compliant compiler.

The main difference for filter support is that explicit SIMD filters using libsimdpp have been dropped while tr2::simd becomes standard and supported by gcc, clang and Visual Studio.

Today, I’m presenting at the ADC my work on analog modelling for the past year.

I will make a more detailed post later this year, but I’d like to put some teasers here. SPICE net lists are an efficient way of representing electronics circuits and there are several very good free and paying simulators. Unfortunately, they are not easy to integrate in a VST plugin.

Audio ToolKit now has a sister project around this topic. The lite version is also licensed under the BSD and can generate a dynamic filter of a net list. The full project is now also capable of generating static filter, with a source file (and compiling it in memory) that can be manually tuned.

Future work on this project will include different solvers for the static filter, as well as a tuner that will be able to drop entries in the Jacobian (full entries or component contributions for a given pin) in the Newton Raphson solver.

After my previous post on SPICE modelling in Python, I need to use a good support example to go up to on the fly compilation in C++. This schema will also require some changes to support more than simple nodal analysis, so this now becomes Modified Nodal Analysis with state equations.

I’m happy to announce the update of ATK Side-Chain Compressor based on the Audio Toolkit and JUCE. It is available on Windows (AVX compatible processors) and OS X (min. 10.9, SSE4.2) in different formats.

This update changes storage format and allows linked channels to be steered by a mix of power coming from each channel, each passing through its own attack-release filter. It enables more creative workflows with makeup gain specific to each channel. The rest of the plugin works as before, with an optional Middle/Side processing as well as side-chain working either on each channel separately or in middle/side.

This plugin requires the universal runtime on Windows, which is automatically deployed with Windows update (see tis discussion on the JUCE forum). If you don’t have it installed, please check Microsoft website.

This entry is part 3 of 3 in the series Playing with a Bela

More than a year ago, I started playing with the Bela board. At the time, I had issues compiling Audio ToolKit with clang. The issue was that the gcc shipped with the Debian image the BeagleBoard used was too old and didn’t fully support C++11. The one that ships now is GCC 6, which is even C++14 compliant. Meaning that everything is available to build Audio Toolkit with Python support.

ATK is updated to 2.3.0 with major fixes and code coverage improvement (see here). Lots of bugs were fixed during that effort and native build on embedded platforms was also fixed.

CMake builds on Linux don’t have to be installed before Python tests have to be ran. SIMD filters are now also easier to implement.
