A beautiful real-time audio spectrum analyzer for iPhone and Android. Live FFT, scrolling waterfall, 1/3-octave RTA, A/C weighting — all processed on your device, nothing ever recorded.
Live FFT trace with peak hold, a log-frequency grid, and a drag cursor that reads out the exact frequency and level under your finger.
A scrolling spectrogram in an ember colormap that makes tones, sweeps, rattles, and intermittent noises impossible to miss.
Spectrum and waterfall together — watch a peak and its history at the same time.
31 bands on the exact base-10 midbands per the IEC 61260 definitions, with hot-band highlighting.
Pink noise, white noise, sine, log sweep and warble tones built in — feed the system under test by cable or USB and watch the response live. No second device, no separate tone app.
Overlay a house curve — flat, −3 dB/oct tilt, or a bass-lifted car target — as a dashed reference over the live spectrum. Auto-fit positioning snaps the shape to your measurement.
Freeze a measurement, recall it as a ghost overlay for before/after comparison, and share a publication-ready image or CSV with a full metadata header.
