- Speaker tests.
- Subwoofer tests.
- Audio amplifier tests.
- Equalizer fine tuning.
- Car audio tuning
- SPL competitions
- Music instrument tuning
- Frequency response analysis
- As a infrasound or ultrasound source
- Subwoofer crossover tuning

This app in only available in the Google Play Store. If you are reading this on another site, do not download the app, it may be an old version, and is not authorized by me. Go to the Google Play please.

- In-app purchases: this permission allows users that want to support the future development and maintenance of this app to upgrade to PRO VERSION, paying a small fee, and without installing a new separate version. This process is the new trend in phone apps. This is a one time purchase only.
- Internet access: This is used only by Google Analytics module, so i can better understand what features are being used.


24 KHz is only possible in phones with a 48KHz sample rate DAC. Some very expensive phones do not have such a DAC. This is a hardware limitation.

    Request that when you save favorites it saves all of the parameters that have been selected not just the frequency.

    This is a great app, especially if your just starting out experimenting with sound frequencies I have used this app for water flow experiments, sand experiments and just to see what frequencies I can use to move/vibrate objects from around my home. Just please be careful, have fun and share your findings with the world. If anyone can figure out how to boil water using sound post it straight to the
