Can this process estimate the phase of the input signal in a given frequency bucket similar to the DFT?
yes - the sample app has demo of single resonator (so frequency bin equivalent) frequency estimation/tracking based on phase shift and also Doppler velocity computation (the code for these is in the Swift package, equations in the upcoming paper...). this video is from an older version of the demo app (less efficient implementation but same principle): https://www.youtube.com/watch?v=iQCPDJ8L_ao
Cool, thanks! I'm currently building a eurorack module where I need to estimate the frequency and phase of a sequence of input gate signals, and an issue I've run into is the delay inherent in the STFT algorithm. This seems like it might work better!
Awesome - The code (Swift or C++) in the Oscillators package is probably the best place to look for implementation details https://github.com/alexandrefrancois/Oscillators
