The art of Virtual Analog filter design [pdf]
- jcelerier 8y agolooks great, see also Julius O. Smith's awesome DSP tutorials: https://ccrma.stanford.edu/~jos/filters/ https://ccrma.stanford.edu/~jos/filters/
- TheOtherHobbes 8y agoReally really useful - good to see NI making this level of detail open and easy to access.
- Junk_Collector 8y agoI think you might want to disambiguate a bit. When people say NI, they are almost always referring to National Instruments, not Native Instruments. Especially considering that both deal in virtual filter implementations.
- jcelerier 8y agoIn audio circles, NI has always been Native first. If I search for "NI Native" in google there is not a single mention of National Instruments in the first page.
- klank 8y agoCan vouch. If talking in music scenes, NI is Native Instruments.
- weatherlight 8y agoNI is Native Instruments, has been that way since the late, late 90's in audio circles
- Junk_Collector 8y agoSure in music circles, but National is pretty big in DSP circles and if I just search NI in google, National Instruments is the first 5 results followed by a news story followed by Native Instruments. If you go to NI.com, that's National Instrument's website. If I search for NI DSP, NI analog, or NI filters all return National Instruments top billing. I think it's reasonable that someone might get confused especially since the PDF (About DSP implementations of Analog Filters) doesn't mention Native.
- myxozoa 8y agoAlways been native instruments in my area. especially simple when commenting on a link from the native instruments website
- joebergeron 8y agoWas this written under the auspices of Native Instruments? If so, I’m extremely impressed - they’re doing some very cool work over there.
- raphlinus 8y agoThis is great stuff. I've also done some work in the space, and did a writeup called "A matrix approach to the Moog ladder filter", which is a pretty different perspective from Vadim's, but the concepts and principles are pretty much the same under the hood. That's the filter in music-synthesizer-for-android, and I think it holds its own, both in audio quality and (SIMD-optimized) CPU efficiency.
