ToneWood

ToneWood helps luthiers, wood suppliers, and instrument makers record and organize acoustic measurements for tonewood. Enter a sample's dimensions and weight, record a tap tone with the iPhone or iPad microphone, and inspect the resulting FFT spectrum. ToneWood calculates useful material parameters from the information you provide, including density, speed of sound, elastic modulus, radiation ratio, acoustic impedance, damping, and quality factor. Features: - Guided dimension and tap-position instructions - Tap-tone recording and FFT spectrum analysis - Acoustic parameter calculations and percentile comparisons - Private sample library synchronized to your account - Optional public sharing of structured measurement results - Printable measurement records with serial numbers and QR codes - Sign in with Apple and email sign-in - In-app account deletion Measurement results depend on the device, environment, wood support, input accuracy, and tapping technique. ToneWood is a workshop analysis tool and does not provide independent laboratory certification.
