What frequency range does the tone generator support?
This tone generator accepts exact frequencies from 20 Hz through 20000 Hz, and the note controls stay inside that same audible range.

Common questions
How do note and octave mode work here?
The note control picks one chromatic note from C through B, and the octave control chooses the register from 1 through 8. Together they calculate the reference frequency automatically using standard equal-tempered tuning with A4 at 440 Hz.
Can I enter an exact Hz value manually?
Yes. Click the frequency readout, type the number you want, and set it directly. This is useful when you want repeatable sound-check or ear-training targets instead of note names.
Does the tone generator stay on my device?
Yes. The tone is generated locally with your device audio engine, so playback starts there without a server-side audio step.
Why start here
G6 is ready the moment this preset opens, which makes it easy to tune by ear, match a starting note, or give a rehearsal group one clear pitch to center on.
How the controls stay flexible
This preset opens in note mode, so you can keep G6 steady, move one chromatic step at a time with the note slider, change octaves, or jump into exact Hz mode when the number matters more than the note name.
When a nearby note helps
If G6 is close but not quite the reference you need, use the nearby preset links to move by one step without losing the quick-start flow.
