Frequency Generator
Manual tones for testing — frequency, waveform, duration, channel and volume.

Frequency Generator
Tones are for testing — not cleaning recommendations. Keep volume comfortable.
When to reach for this
Verifying a rattle you heard during the frequency test, demonstrating what a tone sounds like, or testing one channel at a time. For actual cleaning, the guided cycles sequence multiple frequencies and pulses for you.
Generator FAQ
Can I use this to clean my speaker?
The guided cycles (Water Eject, Deep Clean) are the cleaning tools — they sequence frequencies and pulses deliberately. The generator is for manual testing: verifying a rattle, demonstrating a tone, or experimenting carefully.
Why is the volume capped?
Safety default. The slider tops out at 80% and starts at 40%, and every tone fades in and out. Tones at high gain can be unpleasant — keep it comfortable.
Why only 110–2000 Hz?
The generator covers the range that's useful for speaker testing without inviting ultrasonic or painful extremes. It's a diagnostic aid, not a lab instrument.
