Frequency Sound Generator

Frequency Sound Generator is a compact audio utility for generating and evaluating tones from 0–25,000 Hz with precise manual Hz input. Use it to check headphone and speaker response, test stereo left/right balance, and evaluate bass reproduction. The app also includes an integrated noise meter that uses your device microphone to display approximate decibel readings, and a camera mode that shows on-screen dB values while you view the environment.

Additional features include a Clear Wave function intended to help dislodge light dust or moisture from speakers or microphones (not a guaranteed repair), and simple visual feedback for everyday audio troubleshooting. Frequency is designed for casual testing and preliminary audio checks rather than professional-grade measurements.
