Distortion and Harmonics
Build, draw, or fault-inject a waveform and watch its harmonic fingerprint appear in real time.
Higher = sharper reconstruction, finer spectrum detail & richer auralizer tone (slower to compute)
Common transducer faults, modeled as a distortion of an ideal sine, then decomposed to reveal their harmonic signature.
Click/tap and drag directly on the waveform plot to sketch one period. It decomposes live as you draw.
Load a waveform:
Start with the fundamental plus a couple of harmonics. Add more as needed.
Signal (composite)
Individual harmonic traces
Fourier reconstruction
Harmonic Spectrum (dBFS)
Fundamental
Even harmonics
Odd harmonics
DC offset
Windowed FT contour (leakage)
DC offset: 0.000
Fundamental: 0.000
THD: 0.0%
RB: 0.0%
TD: -∞ dB
TE: -∞ dB
An interactive tool that converts between clean or distorted sine waves and it’s frequency components (e.g. harmonic decomposition). Load presets, draw a wave, or play with the harmonics directly!
