## What is Guitar Tap?

Guitar Tap turns your device into a precision tap-tone analyzer for guitar
builders and tonewood enthusiasts. Tap a guitar body, a raw tonewood plate, or a
brace, and Guitar Tap captures the ring-out, runs a 65,536-point FFT (about
0.67 Hz resolution), and shows you the resonant peaks that reveal how the
structure and material behave.

Built around the tap-tone workflow used by luthiers following Trevor Gore's
methodology — but approachable enough for any builder curious about what their
wood is telling them.

THREE WAYS TO MEASURE

• Guitar mode — Identify the key structural resonances of a finished body: Air
  (Helmholtz), Top, Back, Dipole, and Ring modes. Each peak is labeled with its
  frequency, pitch, Q factor, and bandwidth. See the Tap Tone Ratio and ring-out
  decay time at a glance.

• Plate mode — Measure a rectangular tonewood blank with free-free bending taps.
  Guitar Tap derives Young's modulus along and across the grain, speed of sound,
  specific modulus, radiation ratio, and a quality grade — plus a Gore target
  thickness for your guitar's dimensions.

• Brace mode — A fast single-tap measurement of a brace strip's stiffness and
  quality.

FEATURES

• Real-time spectrum that freezes automatically the instant a tap is detected
• Multi-tap averaging (2–10 taps) to cut noise, with per-tap comparison view
• Color-coded peak labels you can drag, toggle, and reclassify
• Compare 2–5 saved guitar measurements overlaid on one chart
• Save measurements with names and notes; export as files, spectrum images, or
  PDF reports
• Import and share measurements via the Files app, AirDrop, and more
• Microphone calibration support for measurement mics
• Spruce quality scale, anisotropy ratio, and density checks built in
• Play an audio file through the analyzer instead of the live mic

PRIVACY

Everything runs on your device. Guitar Tap has no accounts, no ads, no tracking,
and never sends your audio or measurements anywhere.

Works on iPhone, iPad, and Mac.

### 5/5 — Fantastic tool

*2026-07-30*

This is a fantastic tool for luthiers who want a quantitative understanding of their builds — what works, what doesn’t, and why. I have run spectra on my builds but I have never had this type of comprehensive breakdown of what the results mean. Typically a new app is missing functionality and is buggy. This one is superb.

## Frequently asked questions about Guitar Tap

### What is Guitar Tap used for?

Guitar Tap is a precision tap-tone analyzer designed for guitar builders and tonewood enthusiasts. It measures resonant peaks in guitar bodies, tonewood plates, and braces to reveal how the structure and material behave.

### How does Guitar Tap analyze wood?

It captures the ring-out from a tap, performs a 65,536-point FFT, and displays resonant peaks. For tonewood plates, it can derive Young's modulus, speed of sound, and a quality grade.

### Can I compare different wood samples with Guitar Tap?

Yes, you can compare 2 to 5 saved guitar measurements overlaid on a single chart. This allows for direct comparison of different wood samples or build variations.

### What devices does Guitar Tap support?

Guitar Tap is available for iPhone, iPad, and Mac devices, offering flexibility for users across different Apple platforms.

### How much does Guitar Tap cost?

Guitar Tap is a paid application, priced at $14.99. This one-time purchase grants access to all its features.

### Does Guitar Tap have ads?

No, Guitar Tap does not have ads. The app is designed to run entirely on your device with no advertisements or tracking.

### Can I export my measurements from Guitar Tap?

Yes, you can save measurements with names and notes. These can be exported as files, spectrum images, or PDF reports for further analysis or sharing.

### How often is Guitar Tap updated?

Guitar Tap was last updated on June 29, 2026, with version 1.0.1. This indicates a recent update, suggesting ongoing support and development.

## Version history (last 3 releases)

### 1.0.2 — 2026-08-09

This release rethinks how you measure plates and braces — tap first, then set
the exact dimensions right where you read your results — and makes your saved
measurements easy to back up and carry between devices.

• Set dimensions in the Results — enter a plate or brace's Sample and Body
  Dimensions right where you read them; every property and the Gore target
  thickness recompute as you type. Tap first, enter the exact numbers after.

• Export All / Import — back up every saved measurement to one file, or move
  your measurements to another device.

• iPhone landscape — the Analysis Results now slide in over the spectrum,
  so the chart keeps its full width.

• Clearer material tap names (Longitudinal fL, Cross-grain fC, Diagonal fLC),
  two new Classical panel-stiffness presets, and plate/brace results that
  fill in as you tap.

Plus a range of bug fixes and reliability improvements.

### 1.0.1 — 2026-06-29

• Saved measurements now record the capture sample rate. When you load a
  measurement, Guitar Tap warns if the current microphone's calibration or
  sample rate differs from what was recorded.
• Added a Zoom & Pan help button to the spectrum chart controls.
• Fixed a loaded guitar measurement showing a blank spectrum when the app was
  reopened with the previous measurement being a Plate or Brace (material) one.

### 1.0 — 2026-06-25

No release notes.
