FFT is a real-time spectral analyzer designed specifically for musicians, producers, and audio engineers who demand precision in their frequency domain analysis. This plugin transforms your audio into visual spectrogram, featuring a high-resolution 4096-sample FFT engine that captures every nuance of your sound. With its advanced Blackman-Harris windowing and mel-scale frequency mapping, FFT provides perceptually accurate frequency representation that mirrors how your ears actually hear music. The plugin offers 90dB dynamic range with intelligent color mapping that highlights different frequency bands—from deep blues for sub-bass through vibrant greens for midrange to warm reds for sparkling highs. Whether you're mixing, mastering, sound designing, or analyzing acoustic spaces, FFT's real-time 60Hz display with 75% overlap ensures smooth, responsive visualization that helps you make critical EQ decisions, identify problematic frequencies, monitor stereo imaging, and understand the spectral content of your tracks with scientific precision. The resizable interface adapts to your workflow, making it an indispensable tool for any serious audio professional seeking to visualize and understand their sound in the frequency domain.
Guitar Tap
This app analyzes the resonant frequencies of guitar bodies, tonewood plates, and braces to reveal material properties and structural behavior. It offers detailed measurements for luthiers and wood enthusiasts, with features for comparison, saving, and exporting data.
- Tap-tone analysis for guitars, plates, and braces
- Detailed resonant peak identification
- Derives material properties like Young's modulus
- Multi-tap averaging for noise reduction
- Comparison of multiple saved measurements
- Exportable reports and spectrum images
- On-device processing with no ads or tracking

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.
