ndc Plugs
A number of freeware and open source VST plugins I've written for Windows
and OS X, as well as some resources for plugin programmers.
Subvert Audio
The project I created for my Masters in Music Technology. Unfortunately I
haven't had the time to update it properly. It's usable as it is (well, on
Linux and Windows anyway), but it's still got a number of rough edges I
intended to smooth out.
Tao
A physical modelling programming language written by Mark Pearson. I'm
currently maintaining it as part of my PhD.
ndc Music
Meant to be a sister site to ndc Plugs, but hasn't been updated in ages
(amazingly, it's still there!).
KVR
Very important audio plugin news site.
JUCE
Fantastic cross-platform library, most useful for it's high level audio and
MIDI classes, but also with some very cool gui stuff.
JUCE Forum
Forum to discuss JUCE issues.
PortAudio
Very useful cross-platform audio library.
Album-A-Day
Cool site dedicated to people creating (writing and recording) an album in
one day (24hrs). I've got two albums here myself.
TinyXML
Cool cross-platform xml handling library. Very similar syntax to JUCE' xml
classes, and much easier to understand than libXML (which I still don't
understand).
Open Sound Control
Protocol used to send musical data across networks (i.e. like MIDI but
infinitely more useful for anything other than the most basic piano-style
notation).
