Convert FAUST code to a header-only standalone C++ library. A collection of header files is generated as the output. A class is provided from which a DSP object can be built with methods in the style of JUCE DSP objects.
From the project root:
pip install .The faust2hpp script will be made availalbe in your path by the PIP installation.
faust2hpp --helpFAUST allows converting DSP code to a variety of formats, including standalone plugins. However there doesn't seem to be a good option for integrating the resulting C++ code into a separate codebase.
FAUST does generate C++ code, but it relies on two classes which must be implemented: the Meta and the UI classes.
Moreover, the public interface provided by the resulting code consists of only: initialization, resetting and the compute loop.
There lacks the ability to modify the parameters of the DSP algorithm.
It could be possible to monkey patch some solution involving editing of the generated C++ code. However this isn't a very robust option because a) the code is a private API, so to speak, and can easily change with different FAUST compilation parameters and b) editing C++ code without a full parse is dangerous.
The generated code can provide a public API to the parameters: the parameters exposed by the UI get linked to their UI name.
The idea behind this package then is to create an implementation of the UI class which simply allows access to those public names.
Then, the resulting FAUST class has public access to its parameters.
Moreover, that object is wrapped in a new class which follows the JUCE conventions for DSP objects, and provides getters and setters directly to the variable memory.
- Don't silently fail in the
setParametermethod when the name isn't in the map - Don't copy the
FaustImpl.hheader in the FAUST generated code. - Create a single hader mode
- Add documentation to the script
