vintage - a declarative API for C++ audio plug-ins
This is an experiment in seeing how far modern C++ features allow to write purely declarative code and introspect this code through various reflection-like features.
Building plug-ins
$ g++ \
examples/audio_effect/distortion.cpp \
-std=c++20 \
-I include/ \
-fPIC \
-shared \
-o Distortion.so
Building very very smol plug-ins
The example plug-in can be as small as 6.4kb on Linux:
$ clang++ \
examples/audio_effect/distortion.cpp \
-I include/ \
-O3 \
-march=native \
-std=c++20 \
-shared \
-s \
-Bsymbolic \
-fvisibility=internal \
-fvisibility-inlines-hidden \
-fvisibility-inlines-hidden-static-local-var \
-fstruct-path-tbaa \
-fstrict-aliasing \
-fstrict-vtable-pointers \
-fno-semantic-interposition \
-fno-stack-protector \
-fno-ident \
-fno-unwind-tables \
-fno-asynchronous-unwind-tables \
-fno-plt \
-fvirtual-function-elimination \
-flto \
-fno-exceptions \
-fno-rtti \
-ffunction-sections \
-fdata-sections \
-fuse-ld=lld \
-Wl,-O2 \
-Wl,--lto-O3 \
-Wl,-z,defs \
-Wl,--as-needed \
-Wl,--no-undefined \
-Wl,--gc-sections \
-Wl,--icf=all \
