Hello DSP heads,
The book The Art of VA Filter Design has just been updated to revision 1.1.0 (previously 1.0.3).
As stated by Vadim, the highlights are:
- Transposed Sallen-Key (TSK) filters
- Frequency shifters
- Some other stuff
If you haven't already read this book, you should really do it. I found it extremely useful when I was learning DSP and how filters work, and I still learn from it when I go back and read it from time to time. The filters in it are great too. I love the TPT filter structures. I actually made the (linear) SVF from the book as my first C++ filter project (I come from Reaktor). It's actually a quite simple design. I'll post the link to it just in case anyone is interested. Just note it's a test plugin and I'm very unexperienced in C++. The actual filter is in VAStateVariableFilter(.cpp/.h).
If anyone else implements any of the other filter's in C++ and JUCE, please do share. I'm very interested in how other people implement these designs and algorithms. I plan on making the TPT Ladder Filter when I'm not too busy, so I'll share that too. Maybe someone can get use out of them.
I'm really looking forward to checking out the new things like the TSK filters and the new chapter on frequency shifters. Hopefully y'all can enjoy it too.
Edit: Be sure to check out the KVR thread that Vadim (the author) posted a while back for discussion on this book. He also mentions bugfixes on there first, it seems. There's actually a mistake he already caught, so look out for that.
