Guitar Tap — Support

Tap-tone analysis for guitar builders and tonewood enthusiasts.

Guitar Tap captures the sound of a tap on a guitar, plate, or brace, runs a high-resolution FFT, and reports the resonant peaks and material properties that matter to luthiers. This page covers the most common questions; the full User Manual has detailed walkthroughs for every feature.

Documentation

• Quick-Start Guide — built into the app, under Help (?) on iPhone/iPad, the Help menu on Mac, or the Help button in the browser app.
• User Manual — the complete reference, available from the Help menu (Mac) or Settings → About & Help, and online at dolcesfogato.com/guitar_tap/manual.
• Release Notes — what's new in each version, for both editions, at dolcesfogato.com/guitar_tap/releases.

Frequently Asked Questions

The app asks for microphone access — why?

Guitar Tap needs the microphone to hear your tap. All audio is processed on your device; nothing is recorded for transmission or sent anywhere. If you declined access, enable it under Settings → Privacy & Security → Microphone (iOS) or System Settings → Privacy & Security → Microphone (macOS).

In the browser app, your browser asks for microphone permission the first time you use it — choose Allow. If you declined earlier, re-enable it from the site-permissions control (the padlock or site-info icon at the left of the address bar) or your browser's site settings for the page, then reload.

My tap isn't being detected.

Press New Tap to arm the detector, then tap firmly. If taps are still missed, lower the Threshold slider. If background noise triggers false detections, raise it. A quiet room and a crisp, short tap give the best results.

My plate or brace numbers look wrong.

The calculated moduli depend directly on the dimensions and mass you enter. Double-check length, width, thickness, and mass in Settings → Measurement Type → Material — the app shows the resulting density so you can catch a typo before tapping. Also confirm you are holding the sample at the correct node point (about 22% from one end) as described in the manual.

Where are my saved measurements stored?

Measurements are saved locally on your device in the app's Documents storage. You can export them as .guitartap files, spectrum images, or PDF reports, and share them via AirDrop, the Files app, Mail, and more.

In the browser app, your library is stored locally in the browser itself. Because a browser can clear that storage — Safari deletes it after about a week without visiting the site (on both macOS and iOS) — install the app (Add to Home Screen on iOS, Add to Dock in macOS Safari) for durable storage, and use Export All in Saved Measurements to keep a .guitartap backup you can re-import on any device. Install steps are on the home page.

Can I analyze a recording instead of using the microphone?

Yes. On Mac, use File → Play Audio File to run a WAV or audio file through the analyzer exactly as if it were a live tap. The browser app and the open-source desktop edition offer the same thing via a Play File button.
