Análisis de la app SonoSpec: Audio Spectrum RTA para 8 de octubre

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.
