Frequency detector

Enable the mic and sing or play a tone. Live Hz scrolls as a time series with nearest note lanes (A4 = 440) and cents sharp/flat; the spectrum below shows amplitude vs frequency so you can see harmonics in your voice. Set Sa in the bar below and every lane is named in sargam as well — drone and beat are down there too.

Allow microphone access. Quiet room + steady tone works best.

With the drone on, pitch uses the same tanpura signal the bar is playing (reference cancel) plus synth cleanup. Mic mode Speakers turns off browser echo cancellation so that works at volume. Steady Sa bleed may still be ignored when the checkbox above is on.
