## What is Tuning Fork Studio?

Tuning Fork is a tool for tone generation, instrument playback, and sound observation. Build a sound from a familiar reference pitch, then explore it through live waveforms and spectra.

Customize frequency, output gain, and harmonic components. Choose sine, square, triangle, or sawtooth waves, layer harmonics, and save configurations for later use.

Play notes on a piano keyboard with the included GeneralUser GS soundfont. With microphone permission, the analyzer shows a live waveform, frequency reading, input level, and spectrum on your device.

Core instrument playback, custom frequency, basic waveforms, and sound analysis are free. Pro adds the complete instrument library, more waveforms, unlimited sound configurations, and longer audio exports. Prices and availability are shown in the App Store.

The app does not collect your data. Microphone input is processed on-device for live analysis and is not uploaded to developer servers.
