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.
A few months ago, I started playing with the Bela board. At the time, I had issues compiling Audio ToolKit with clang. Since then and thanks to Travis-CI, I figured out what was going on. Unfortunately, the Beagle Board doesn’t have complete C++11 support, so I’ve added the remaining pieces, and you need also a new Boost.
I have now some time to play with this baby:
The CPU may not be blazingly fast, but I hope I can still do something with it. The goal of this series will be to try different algorithms and see how they behave on the platform.
There are so many different distortion/overdrive/fuzz guitar pedals, and some have a better reputation than other. Two of them have a reputation of being closed (one copied on the other), and I already explained how one of these could be modeled (and I have a plugin with it!). So let’s work on comparing the SD1 and the TS9.
I’m currently considering whether I should do more posts on preamps modeling or just keep implementing filters/plugins. Of course, it’s not one or the other, there are different options in this poll:
So the idea is to ask my readers what they actually want. I can explain how the new triodes filters are implemented, how they behave, but I can also add new filters in Audio Toolkit (based on different preamp and amp stages, dedicated to guitars, bass, other instruments), try to optimize them, and finally I can include them in new plugins that could be used by users. Or I can do something completely different.
So if you have any ideas, feel free to say so!
ATK is updated to 1.3.0 with new features and optimizations.
Update: It seems I have misunderstood the DK method, so instead I’m using a variation of the Nodal Analysis, so this can be understood as a state-space MNA method.
When analyzing a circuit form scratch, we need to replace all capacitors by an equivalent circuit and solve the equation with this modified circuit. Then, the equivalent currents need to be updated with the proper formula.
Let’s dive directly inside the second diode clipper and follow exactly the same pattern.
