This is the codebase on which RS-MET products are based. My main and most important codebase - my lifework, so to speak. If you want to use the code in an open source project, feel free to do so (but please notify me and give proper credits and if you use any of the JUCE based code, be sure to adhere to its licensing scheme, too). For closed source projects, you may purchase a commercial license. I negotiate the conditions individually, based on the size of the product/company, the role of my code within it, etc.
The codebase ist structured as follows:
The "Libraries" folder contains a "RobsJuceModules" subfolder which contains a couple of my own JUCE modules, conforming to the way, JUCE itself is organized into modules. The rapt module (Rob's Audio Processing Templates) is a template based library with rather low level code for math, number crunching and signal processing. It has no dependencies whatsoever (not even on juce_core). The rosic module (Rob's Signal Processing Classes), which depends only on rapt, is a bit more high-level and more convenient to use and even includes some framework'ish stuff (like thread-synchronization, polyphonic voice-management, etc.) to facilitate easy integration of the code into plugins. rapt and rosic, although conforming to juce's module organization, do not depend in any way on juce. They can be used in their own right and/or combined with other frameworks. jura_framework is my juce-based GUI and plugin framework and jura_processors is the glue that ties together the DSP code from rapt/rosic with the jura_framework based GUI code into actual plugins or sub-modules of plugins (such as oscillators, filters, effects, etc.).
The most important project that can actually be built by itself is in: Products/AudioPlugins/ToolChain/ ToolChain is a plugin that is actually many plugins in one. You can create a chain of several sound processors (which i internally call AudioModules) that were previously distributed as plugins in their own right. Project management is just sooo much easier when everything is lumped into a single project. The code in this project is trivial because all the actual code is in the library. The other projects that can be built are mostly for development and testing.
Disclaimer: I'm currently in the process of restructuring the codebase, merging code from 3 different codebases with lots of overlapping functionality but slightly different goals and interfaces. That is to say: it's rather messy at the moment and the API is still subject to change. Eventually, my goal is to provide a commercially viable DSP library for licensing to audio software companies - but as said: i need to clean up a lot of things, so don't take the messy and inconsistent API too seriously yet - i'm still working on it (we are pre version 1.0 at the moment). ...and if you have some special requirement that the library does not yet support - consider to hire me to add it. I'm generally available for freelance work on audio DSP algorithms with special interest in musical DSP.
for a quick overview for what i'm planning for rapt library, you may take a look at this horribly incomplete, outdated, skeletal document: https://github.com/RobinSchmidt/RS-MET/blob/master/Documentation/RAPT/LaTeX/UserManual/UserManual.pdf
