Export functionality is planned—current focus is on real‑time generation, sweeps, binaural beats and multi‑oscillator layering.

Frequency Sound Generator App

Q: How accurate are the generated frequencies?

Frequencies are generated using high‑precision Web Audio APIs, typically within 0.1 Hz accuracy depending on device clock stability.

Q: Does it drain battery?

Normal usage is efficient; very high volume or continuous multi‑oscillator playback increases consumption like any audio app.

Q: Can I use it for hearing tests?

Yes, it can approximate hearing range checks, but it is not a certified medical audiometry tool.

Precise & Reliable

Exactly what I needed for calibrating equipment. The frequency sweep and multi-oscillator features are spot on.

Great for practice

I use the metronome and tuner daily. Clean UI and fast performance. Replaced two other apps.

Frequently Asked Questions

Is the web version limited?

Yes. The browser demo focuses on core tone generation so it loads instantly. The app adds presets, export, advanced tools and offline performance.

Does it work offline?

The installed app works fully offline; the web demo may pause if the browser suspends the tab or you lose connection.

How accurate are the generated frequencies?

They are sample-accurate within the device sample rate. The native app reduces drift and latency even further for high‑precision testing.

Will more features be added?

Yes. Roadmap: cloud preset sync, modulation matrix, spectral & waveform analyzers, batch export, and automation tools.

Is there any cost?

Core tools stay free to try. Advanced & pro modules in the native app support ongoing development.

Why install instead of just using the site?

Lower latency, background audio, offline reliability, unlimited presets, exporting sweeps, advanced generators, and future pro modules.

Can I export audio?

Yes, in the app you can export sweeps and custom tones for sharing or external analysis.

Does it drain battery?

Continuous high volume / high frequency playback can use more battery. The app includes optimizations and quick mute controls.

Can I use it for hearing tests?

It can help with informal checks, but it is not a medical diagnostic tool. For certified testing consult a professional.
