Frequently asked questions
What frequency should I use?
Any you like within 20–20,000 Hz. 440 Hz is the standard 'A' used for tuning; 432 Hz is a popular alternative. Start quiet and adjust.
Do I need headphones?
No, but they give a cleaner tone. Keep the volume moderate — pure tones can be surprisingly harsh.
