FAQ
Tool questions
Do I need an account?
No. Scores for the trainers stay in this browser's local storage. Clearing site data clears them.
Are the tool URLs with query strings separate pages?
No. /tone-generator/?f=440 and /metronome/?bpm=120 are views of those tools. The indexable references are the frequency and BPM pages linked from here.
How loud should I listen?
Keep generators at a conversation level. These pages can generate steady tones and noise, which fatigue your ears faster than music. If anything rings or feels uncomfortable, stop and turn the volume down.
