Does BeatNet have a C or C++ interface?

[aroffringa]

Hi! I'm quite impressed by BeatNet. I was wondering if it is possible to use BeatNet from C++?

Hi! We have managed to port the streaming mode here: https://github.com/pasquale90/BeatNet/tree/main/onnx. In case you test this, I would appreciate letting me know if it works on your end.

I appreciate you sharing a ported version @pasquale90 - the effort to run an onnx model in C++ alone can be onerous. I know this through my own personal and occasionally painful experience.

Should others look into adopting or using some of the C++ code, I would highlight two current omissions:

• The frame processor class does not take 'hop size' into account. It currently dispatches whatever the latest written data is, if it satisfies the 'frame size' criteria. I'm not deeply familiar with BeatNets behavior so the impact of this might be negligible, but I'd expect the network to function best if the data provided to process was at even intervals with some sort of hop size reflected.
• The particle filter - which is essential for BeatNet to properly estimate beats and downbeats - is currently unimplemented.
