Can you please try to be more specific? What is the drop of a song? Are you talking about drag and drop functionality?

I mean when the bass drops and the good part of the song comes 🙂. At what point in the timeline of the song.

If you’re just trying to see the waveform, use this: [https://www.sonicvisualiser.org/](https://www.sonicvisualiser.org/)

Here are some papers on automatic detection of “the drop” in music analysis:

I believe that p5.sound is fairly limited in terms of built-in analysis – it has fft and amplitude.
