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.
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.
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.
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.
