# GENERATE ANY TONE, FROM 1 HZ TO 40 KHZ
Frequency is a tone generator. Set a pitch by hertz or by note and octave, choose a waveform, and play it. It also plays the low sweep that pushes water out of a blocked speaker.
# PLAY A TONE AT ANY FREQUENCY
Enter a value in hertz, or pick a note and an octave and let the app work it out. The range runs from 1 Hz to 40,000 Hz, past the top of human hearing.
# CHOOSE YOUR WAVEFORM
Sine, triangle, sawtooth, and square. Each has its own character, and switching between them at the same pitch is the quickest way to hear the difference.
# PLAY SEVERAL TONES AT ONCE
Run more than one tone together, each with its own frequency, waveform, and volume, and listen to how they interact.
# CLEAN YOUR SPEAKER
Water trapped in a speaker muffles it. Playing a low-frequency tone at full volume vibrates the driver and pushes the water out — the same technique a smartwatch uses to eject water after a swim.
# A REFERENCE PITCH TO TUNE AGAINST
Play a note at a known frequency and tune your instrument to it by ear. Frequency plays the reference; it does not listen, so nothing you play reaches the app.
# TUTORIALS INCLUDED
Step-by-step guides for generating tones, working with waveforms, running several at once, and cleaning a speaker.
