About SonoSpec: Audio Spectrum RTA
SonoSpec turns your phone's microphone into a beautiful real-time audio spectrum analyzer. Built for car-audio tuning, room acoustics, HVAC and machinery noise hunting, speaker testing, and anyone who wants to SEE what they're hearing.
FOUR VIEWS, ONE INSTRUMENT
• Spectrum — live FFT trace with peak hold and a log-frequency grid
• Waterfall — scrolling spectrogram that makes tones, sweeps and rattles obvious
• Split — spectrum and waterfall together
• Octave — 31-band 1/3-octave RTA bars
MEASUREMENT-GRADE DETAILS
• FFT sizes from 2,048 to 16,384 points (5.9 Hz resolution at 48 kHz)
• A, C and Z weighting curves computed per the IEC 61672 formulas
• Exact base-10 1/3-octave bands per the IEC 61260 definitions
• Peak-hold trace with slow decay, pause/hold, and a drag cursor that reads out the exact frequency and level under your finger
• Levels in dBFS with a proper full-scale sine reference and window-bandwidth (ENBW) correction — the numbers mean something
BUILT-IN SIGNAL GENERATOR
• Pink noise, white noise, sine, log sweep and warble tones — the source half of the RTA workflow
• Feed the system under test by cable or USB and watch the response live
TARGET CURVES
• Overlay a house curve — flat, −3 dB/oct tilt, or a bass-lifted car target — on the live spectrum
• Auto-fit positioning: the shape snaps to your measurement, no fiddling
SNAPSHOTS & EXPORT
• Freeze a measurement and recall it as a ghost overlay for before/after comparison
• Share a publication-ready image or CSV with a full metadata header — FFT size, window, weighting — so your data still means something later
TUNED TO FEEL LIKE HARDWARE
Rendering runs on a dedicated Metal graphics path at the full analysis rate, with a phosphor-and-ember instrument look that's readable at arm's length.
PRIVATE BY CONSTRUCTION
Audio is analyzed on-device and never recorded, stored, or transmitted. SonoSpec has no accounts, no ads, no analytics — the app cannot even access the network.
One-time purchase. No subscriptions.
