myk-polypitch-detect-plugin

VST plugin that does realtime polyphonic audio to MIDI conversion

Preparing to build

git clone https://github.com/yeeking/myk-polypitch-detect-plugin.git
cd myk-polypitch-detect-plugin
cd ThirdParty
# I always mess up submodules so do this instead:
git clone https://github.com/juce-framework/JUCE.git
git clone https://github.com/jatinchowdhury18/RTNeural.git
cd ..
./build-prep.sh

then to actually do the build - on the CLI

cmake -B build .
cmake --build build --config Release -j 20

Debug vs Release build

• The Debug build on my AMD Ryzen 7840U machine can analyse one second of audio in 2.6 seconds. So don't expect realtime with the Debug build!
• The Release build on the same machine does one second of audio in 0.026 seconds, allowing for realtime use with a one second latency.

Most of the clever code is from NeuralNote...

I am claiming minimal credit for the hard stuff in this project: see https://github.com/DamRsn/NeuralNote which I enthusiastically borrowed from. I have retained the Apache license from that project and left all credits in source code where they were.

TODO

• [done] apply downsampling to buffer prior to note extraction as per neuralnote
• possibly apply post processing on notes as per neuralnote
• write some proper tests to eveluate frame-> frame overlaps etc.
