Announcement: ATKLimiter 1.0.0, ATKCompressor 1.1.0, ATKExpander 1.1.0

I’m happy to announce the release of one new limiter plugin based on the Audio Toolkit. It is available on Windows and OS X (min. 10.8) in different formats. I also updated the compressor and the expander with improved UI controls. The compressor also has now a dry/wet knob, allowing to use it for parallel compression.

Audio Toolkit: ATKCompressor and ATKExpander Implementation

I’d like to talk a little bit about the way a compressor and an expander can be written with the Audio Toolkit. Even if both effects use far less filters than the SD1 emulation, they still implement more than just one filter in the pipeline, contrary to a fixed delay line (another audio plugin that I released with the compressor and the expander).

Announcement: ATKCompressor 1.0.1, ATKExpander 1.0.1

I’m happy to announce the release of two new audio plugins based on the Audio Toolkit. It is available on Windows and OS X (min. 10.8) in different formats.

Audio Toolkit: ATK SD1 Implementation

I just released my SD1 simulation, and now it is time to explain why is inside this plugin. Not everything in the original pedal was simulated, and different schemes were used to tackle the different stages.

Announcement: ATK SD1 1.0.0

I’m happy to announce the release of my third audio plugin, the first based on the Audio Toolkit. It is available on Windows and OS X in different formats.

The UI was designed by Florent Keller, many thanks to him!

Announcement: Audio TK 0.2.0

It’s time for a new release of the toolkit. Much has been done in terms of basic filters, but also to simplify usage (static and shared libraries are compiled, no need to reset the pipeline before calling process…).

Audio Toolkit: Optimization of the overdrive simulation

I’ve explained in earlier posts how to simulate a simple overdrive circuit. I’ve also explained how I implemented this in QtVST (and yes, I should have added labels on those images!), which was more or less the predecessor of Audio TK.

The main problem with simulating non linear circuits is that it costs a lot. Let’s see if I can improve the timings a little bit.
