Frequently asked questions
+What frequency range can I generate?
20 Hz to 20,000 Hz, the commonly cited range of human hearing. What you actually hear depends on your speakers and your ears.
+What's the difference between the waveforms?
Sine is a pure tone. Square, sawtooth and triangle add harmonics, sounding buzzier — useful for checking distortion.
+Can high frequencies damage my hearing?
Any loud sound can. Keep volume low, especially with headphones and at high frequencies you may not perceive as loud.
