| May 2, 2024 at 18:49 | comment | added | Joshua Sullivan | I just used a 20-20kHz YouTube video to test... the 2nd bucket suddenly activated around 6.5kHz, the 3rd at 13kHz, and the 3rd between 18-19kHz, just before the video ended. I completely understand what's going on now, thank you so much. | |

| May 2, 2024 at 16:18 | comment | added | Joshua Sullivan | Point taken. I'm playing a little fast and loose as this is just for a simple animation, not a scientifically or statistically valid analysis of a waveform. | |
| May 2, 2024 at 14:58 | comment | added | Juha P | Use sweep etc. generated audio signal for testing purposes ... . Soprano goes little above 1kHz (+ few harmonics) so, if bins in your implementation covers whole frequency range (0 - 22.05kHz @ 44.1kHz sampling) you sure understand that using vocals in testing your software is not the best practice. | |
| May 2, 2024 at 12:28 | comment | added | Joshua Sullivan | So the microphone produces 44.1kHz, 16-bit audio. I suppose I could re-jigger it to run off an imported sound file, but that's not really the use-case for the final implementation. I played some opera with sopranos singing VERY high notes and still only my bottom quarter of bins (0-255) showed any movement. | |
| May 2, 2024 at 7:00 | comment | added | Juha P | What type of data are you using in your testing (is it mic input only?) ? You could try by feeding 0 - Fs/2 sweep signal (constant amplitude) from file? | |
