SoundScope: Light

Turn your iPhone into a pro audio lab: real-time spectrum, broadcast-grade LUFS, and a mix-diagnostics engine that tells you what to fix. No setup. No subscription.

See your sound.

SoundScope turns your iPhone and iPad into a complete audio analysis instrument — spectrum, loudness, stereo field, and dynamics, measured with broadcast-grade precision and rendered in a stunning brushed-metal interface.

Whether you're mixing, mastering, running live sound, tuning a room, or you simply love watching music breathe, SoundScope shows you what your ears alone can't catch — and tells you how to fix it.

— FOUR WAYS TO SEE YOUR SOUND — • SPECTRUM — high-resolution real-time analyzer with bars or silky line mode, animated peak hold, 20 to 120 bands, logarithmic or linear scaling • SPECTROGRAM — scrolling waterfall with a gorgeous inferno heat map, 20 Hz to 20 kHz • RADIAL BLOOM — an ambient circular analyzer with a core that pulses to the beat • RIBBON TUNNEL — a mirrored neon ribbon that turns your desk into mission control

— BROADCAST-GRADE LOUDNESS — A full ITU-R BS.1770 loudness suite: Momentary, Short-term, and gated Integrated LUFS, Loudness Range (LRA), intersample True Peak (dBTP), and a DR dynamics score. Know exactly how loud you are before you upload — not after.

— A MIX ENGINEER IN YOUR POCKET — The built-in diagnostics engine listens with you and speaks plain English: clipping alerts, loudness-war warnings, crushed dynamics, mono sub-bass cancellation, and frequency-balance issues — all judged against genre profiles for EDM, Hip-Hop, Rock, Classical, Acoustic, and Podcast. It even tells you how far streaming platforms like Spotify and YouTube will turn your track down.

— READ THE STEREO FIELD — Stereo VU meters with peak hold, a live stereo-image scope, Mid/Side spectra, and a phase-correlation meter. Per-band RMS from sub to air, plus a mono-compatibility strip that shows exactly where your mix collapses in mono.

— SURGICAL CONTROL — FFT sizes from 64 to 131,072 with TRANS / BAL / MASTR presets, overlap up to 93.75%, HOLD to freeze and inspect any moment, and input sensitivity from 0.1x to 4x.

— ANY SOUND. ZERO SETUP. — Point it at your studio monitors, a live PA, an instrument, or a track playing back — through the built-in mic or any connected audio interface. Rotate to portrait for full metering, landscape for the analyzer.

— DESIGNED TO BE LIVED IN — A luxurious brushed-metal instrument with tactile controls, haptic feedback, and eight accent themes — including a live per-frequency Spectrum rainbow. Full dark-mode and Reduce Motion support.

— PERFECT FOR — • Studio engineers, producers, and mastering • Live sound and FOH engineers • Musicians, vocalists, and podcasters • Acousticians, installers, and educators • Anyone serious about sound

No subscriptions. No accounts. No sign-in. No telemetry. Everything runs on-device and offline, with Apple-native engineering that stays silky-smooth on iPhone and iPad.

Stop guessing. Start seeing. Download SoundScope and hear with your eyes.
