## Description

The Hertz Frequency Generator Chrome extension enables users to generate sound frequencies ranging from infrasonic 0Hz up to ultrasonic 25kHz. It supports multiple waveforms including sine, square, sawtooth, and triangle within the 50Hz to 16kHz range, making it versatile for various applications such as audio testing, relaxation, meditation, and sound therapy.

Features include pink noise and beep generation, oscillators for continuous waveforms, and multi-frequency harmonic creation. This tool can function as a Rife machine, 528Hz or 432Hz sound wave player, tinnitus relief aid, dog whistle generator, and more. Its user-friendly interface allows transformation of your device into a dynamic sonic frequency tool suitable for professional, educational, or personal use.

## Review summary

Users praise Hertz Frequency Generator for its multi-oscillator feature, ease of use, and versatile applications like speaker tuning and therapy. However, repeatedly mentioned issues include difficulty setting precise frequencies due to sensitive controls and lack of manual input, inability to run continuously in the background as it stops playing when minimized or screen times out, intrusive ads interrupting usage, and limited frequency scale and features like presets. Despite its flaws, it remains a useful tool for audio frequency generation tasks.

### Pros

- Offers multiple oscillators allowing intermodulation measurements and multiple frequency generation.
- Useful for various purposes including speaker tuning, tinnitus therapy, animal control, meditation, and sleep aid.
- Simple and easy to use interface appreciated by many users.
- Effective in generating frequencies even with the phone's limited speaker capacity.
- App works well as a frequency generator and tone source for experiments and practical use.

### Cons

- Inability to manually input exact frequencies, making precise tuning difficult due to sensitive and jumpy dials.
- App stops playing sound or shuts down when minimized or when the screen times out, limiting background use.
- Advertisements disrupt usage flow, sometimes starting multiple frequencies unintentionally and requiring force close to stop.
- Some users find the frequency scale limited (e.g., default 440 Hz instead of preferred 432 Hz) and lack of presets or extensive waveform options.
- Notifications and ads can be intrusive and frequent, leading to user dissatisfaction.
