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 \
  -o Distortion.so

$ du -b Distortion.so

Lightweight Embedded Audio Framework

LEAF (Lightweight Embedded Audio Framework) is a C library for audio synthesis and processing created by Jeff Snyder, Mike Mulshine, and Matt Wang at Princeton University's New Instrument Research Lab. It was originally called OOPS when we started writing it in 2017, so you may see references to it under that name as well.
