When I started reviewing the diode clippers, the goal was to end up modeling a triode simple preamp. Thanks to Ivan Cohen from musical entropy, I’ve finally managed to drive the proper equation system to model this specific type of preamp.
After my transient shaper, some people told me it would be nice to have a splitter: split the signal in two tracks, one with the transient, another with the sustain. For instance, it would be interesting to apply a different distortion on both signals.
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 happy to announce the release of a mono transient shaper based on the Audio Toolkit. They are available on Windows and OS X (min. 10.11) in different formats.
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.
Audio Toolkit shines when the pipeline is fixed (filter-wise and parameter-wise). But in DAWs, automated parameters are often used, and to avoid glitches, it’s interesting to additionally smooth parameters of the pipeline. So let’s see how this can be efficiently achieved.
I’m happy to announce the release of a mono autoswell based on the Audio Toolkit. They are available on Windows and OS X (min. 10.8) in different formats.
This plugin applies a ratio to the global gain of a signal once it is higher than a given threshold. This means that contrary to a compressor where the power of the signal will never go lower than the threshold, for AutoSwell, it can.
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.
