The main changes for this release are first trials at modulated filters, C++11 usage (nullptr, override and final), and some API changes (the main process_impl function is now const).
Sometimes images are worth a thousand words, so let’s look at some pictures of a middle-side compressor behavior.

I’m happy to announce the release of a stereo compressor based on the Audio Toolkit. It is available on Windows and OS X (min. 10.8) in different formats. This stereo compressor can work on two channels, left/right or middle/side, possibly in linked mode (only one set of parameters), and can be set up to mix the input signal with the compressed signal (serial/parallel compression).
I’m happy to announce the release of a mono fixed delay line based on the Audio Toolkit. It is available on Windows and OS X (min. 10.8) in different formats. The three knobs adjust the direct signal (blend), the delayed signal (feedforward) as well as the feedback signal from the delay line injected in the input. The delay can be set from 0 ms to 1 s by steps of 0.1 ms.
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 is now almost ready for its first stable release. Its content will now move toward more advanced DSP algorithms (zero delay filters, amplifiers).
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).
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.
A lot has happened in two weeks for Audio ToolKit. This release mainly adds tools for Compressor and Delays design. There will be additional plugins release soon.
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.
