This looks like it could be useful to a lot of people, from developers to tinkerers and Max users and lots of other people too.
Here’s what the site says:
RTcmix is a real-time software “language” for doing digital sound synthesis and signal-processing. It is written in C/C++, and is distributed open-source, free of charge. In certain respects, it is similar in function to other extant unit-generator-based software languages such as CSOUND, SuperCollider and (to a lesser extent) JSyn and Max/MSP — they do share a common heritage, after all. There are some differences, however, between all these languages… and variety is of course the spice of life!
So if you’ve been searching the web high and low for just the right library of DSP functions to include in your latest & greatest “killer” (or maybe “peacefully coexisting”?) app, then RTcmix may just be the Right Package for You.
