  • And this is a tuner using same algorithm: https://apps.apple.com/us/app/resonance-chromatic-tuner/id16...

    Also very old stuff :)

  • I don’t like the bins drifting from so far away so slowly. There needs to be repulsive force that prevents the bins from colliding.

    It would be interesting if the resonators could adaptively model timbre to factor out harmonics while still handling unique timbre at each frequency. That could produce a pitch diagram color coded by instrument.

    Edit: I bet you could fork a resonator and run over the window it just finished in reverse to correct the drift.

  • I have such app for more than 4 years. Your algorithm is not new - it is new for you only :) Here is the app: https://play.google.com/store/apps/details?id=com.bialamusic...

  • Slowed down higher pitch example was nice to hear, as this is where often conventional methods are heavily artifacted

  • A useful demo for this kind of tool would be a side-by-side on difficult inputs: fast pitch bends, dense chords, and low-SNR recordings. Latency is easy to appreciate visually, but robustness under messy audio is what usually decides whether spectral tools become part of a workflow. Even a small set of repeatable test clips would make the tradeoff much clearer.

  • REMINDER! You can not put your name under something that is on the market since 2019 in several products with more that 100K users just because you wrote some paper in 2025! You may use it, you may describe it, you may try to improve it but you can not title yourself an inventor :) You are just late to this!

  • Why the author is acting hostile ?? Here is description of my method for frequency detection using resonance sensors from 2019! https://bialamusic.com/resonance_frequency_detection/

    If you want to cooperate - I am open for that and I can share more. But this is public knowledge and should stay that way. Why you are deleting my comments in youtube - I have apps with 100K+ installs using such method and I can share details if you are really interested

  • Nice. To the folks saying "nothing to see here" this appears to be a variation of filter-bank spectral analysis where each band varies in frequency to track "the" in-band sinusoid. Somewhat like a bank of PLLs each with its own tracking bandpass filter. By using IIR filters rather than FFTs you avoid the latency of buffering up a full frame of data before you can run the FFT analysis. I am curious how this handles input containing broadband transients. It might be interesting to use CIC filters rather than an IIR lowpass to get better time selectivity, but maybe that's already been addressed, I didn't read the papers.
