SoundScope: Audio Analyzer

v1.7: see your sound. RADIAL BLOOM, SPECTROGRAM and RIBBON TUNNEL — three new full-screen visualizations at a locked 60fps. Double-tap to cycle. Still no subscription.

SoundScope turns your iPhone into a professional audio analysis suite. Whether you're deep in a mix, finishing a master, recording a podcast, or just want to know what's actually going on with your sound — you've got the tools now. The real ones. The ones the pros use.

And it fits in your pocket.

-- LOUDNESS, DONE RIGHT --

Spotify normalizes to -14 LUFS. YouTube to -13. Netflix to -27. Get it wrong and your mix gets turned down, mangled by encoders, or just sounds off on the other end. It happens to everyone — until they start measuring.

SoundScope runs full ITU-R BS.1770-4 compliant loudness metering: • Momentary LUFS (400ms window) • Short-Term LUFS (3s window) • Integrated LUFS with proper two-pass gating • Loudness Range (LRA) for dynamic variation • True Peak with sub-sample interpolation • PLR — your personal Loudness War detector • Dynamic Range (DR) score

Real platform targets, right on screen. Hit them every time.

-- SPECTRUM ANALYZER FOR PEOPLE WHO CARE --

Rotate to landscape and SoundScope opens up into a full-frequency spectrum analyzer with serious depth behind it.

Three FFT modes: • TRANS (1024) — catches fast transients the moment they hit • BAL (4096) — smooth, balanced, great for mixing • MASTR (32768) — surgical frequency detail for mastering

Overlap from 25% to 93.75%. Log or linear scaling. 20 to 120 frequency bands. Freeze with HOLD for a detailed read. Double-tap to cycle visualizations.

This is not a toy spectrum analyzer.

-- FIVE WAYS TO SEE YOUR SOUND --

Double-tap the analyzer and cycle through five full-screen visualizations:

• SPECTRUM BARS — the classic. Precise, readable, honest. • SPECTRUM LINE — a smooth curve that makes resonances jump out • RADIAL BLOOM — your spectrum as an aurora, blooming out from the center • SPECTROGRAM — frequency over time in an inferno colormap. Watch your whole track scroll past. • RIBBON TUNNEL — mirrored ribbons flying through space

Locked 60fps. Every mode follows your theme color. Beautiful enough to leave running on the desk — accurate enough to mix on.

-- BAND RMS: ACTUALLY BALANCE YOUR MIX --

Five frequency bands. Real dB RMS values. Instant read on whether your mix is balanced — or whether your sub is eating everything alive.

• SUB (20–80 Hz): Is your sub eating the mix? • LOW (80–250 Hz): Kick and bass sitting right? • MID (250 Hz–2 kHz): The muddiness danger zone • HIGH-MID (2–8 kHz): Presence, clarity, harshness • AIR (8–20 kHz): Brightness and top-end extension

Mono compatibility scores per band — because nothing is worse than your bass disappearing on a phone speaker.

-- DIAGNOSTICS: A MIX CONSULTANT IN YOUR POCKET --

Tell it the genre. Get real-time feedback on your mix.

Diagnostics knows the difference between an EDM master and a classical recording. It knows what a podcast should sound like versus a hip-hop banger. Set your genre target and it watches your levels, your dynamics, your frequency balance, and your mono compat — and tells you exactly what's off.

Seven genre profiles: General, EDM, Hip-Hop, Classical, Rock, Acoustic, Podcast.

No guessing. No Googling "how loud should my mix be." Just answers.

-- STEREO & PHASE --

• Phase Correlation Meter — from -1 (phase disaster) to +1 (mono-safe) • Stereo Spread Visualizer — see your stereo image, not just hear it • M/S Decoding — separate center and side content • Per-frequency mono compat — find exactly where your stereo breaks in mono

-- VU METER --

60-segment LED-style metering for Left and Right channels. Smooth, precise, peak hold. Color-graded from blue to red. The classic tool, rebuilt for the modern screen.

-- BUILT FOR REAL WORKFLOWS --

• USB audio interfaces supported • Bluetooth A2DP input • External microphones • Adjustable input gain (0.1x – 4.0x) • 7 theme colors • No subscriptions. No ads. No nonsense.

SoundScope is the one you reach for when you need to know what's really happening in your audio.
