SoundScope: Light

Test our professional-grade audio analysis on your Mac. Real-time FFT spectrum analyzer, stereo metering, and M/S analysis — all in one stunning, dark-themed interface.

This is SoundScope: Light — the light version of our app SoundScope Pro. SoundScope Pro is the professional audio spectrum analyzer built for Mac. Whether you're mixing a track, mastering a record, designing sound, or just curious about what your music looks and sounds like under the hood — SoundScope Pro gives you the precision tools to hear what your ears alone can't catch.

— REAL-TIME FFT ANALYSIS — At the heart of SoundScope Pro is a high-resolution FFT engine with configurable sizes from 64 all the way to 32,768 — giving you everything from ultra-fast transient response to surgical frequency precision. Switch between TRANS, BAL, and MASTR presets instantly, or dial in the exact FFT size and overlap you need.

— VISUALIZE YOUR AUDIO, YOUR WAY — Choose between two stunning visualization modes: crisp frequency bars with animated peak indicators, or a silky-smooth line graph with filled gradient area. Toggle logarithmic or linear frequency scaling. Set 16, 32, 64, or 128 bands. Freeze the display instantly with HOLD mode to analyze any moment in time.

— FULL STEREO & M/S ANALYSIS — SoundScope Pro goes beyond a simple frequency visualizer. Monitor your Left and Right channels simultaneously with accurate VU meters and peak hold. Inspect stereo width with the Stereo Image visualizer. Analyze your mix in Mid/Side with dedicated M and S spectrum displays. Watch phase coherence in real time with the Phase Correlation meter — essential for mono compatibility checks.

— SYSTEM AUDIO, ZERO SETUP — Capture your Mac's system audio output directly using Apple's ScreenCaptureKit — no virtual audio driver, no third-party installs required. Switch seamlessly between system audio loopback and any connected microphone or audio interface.

— BUILT FOR PROFESSIONALS, DESIGNED FOR MAC — A dark, premium interface with 7 accent color themes. Rotary faders for sensitivity and overlap control. Persistent settings across sessions. Designed to live permanently on your desktop while you work.
