Hi all[Edit: Nov 27, 2018 added link to ADC2018 presentation]Here it is: The Art of VA Filter Design . It is based around the TPT (a.k.a. zero-delay feedback) filter design method. No preliminary filter design knowledge required.Mirror:Older revisions: http://www.native-instruments.com/filea ... _1.1.1.pdf (NI website) http://www.discodsp.net/VAFilterDesign_1.1.1.pdf (thanks to george for mirroring)The book has been actually written in the last week of April, but there were some unforseen delays getting it published. In the meantime I replaced the originally used DF2 integrators with TDF2 integrators (thanks to mystran). It's remarkable how at the very same time the same topic got extensively discussed on KVRThe book text hasn't been extensively proofread, so if you spot any mistakes, the feedback is welcome. Equally, I would appreciate the mirroring of the file, in which case please drop me a note, so that I can inform you of the updates.The ADC2018 presentation of the 2nd revision of the book is here https://www.youtube.com/watch?v=zPzCLqkQnr0 Enjoy!Regards,Vadim
