SoundScope Pro

You hear the problem — a low-end buildup, a harsh high-mid, something slightly off in the stereo field. But finding it fast takes tools most engineers pay monthly fees for.

SoundScope puts pro-grade audio analysis on your Mac. Permanently. For free.

Watch your full frequency spectrum come alive from 20Hz to 20kHz with bar or smooth line visualization. Choose logarithmic or linear scaling. Set frequency bands from 20 to 120. Dial in FFT size up to 131,072 samples and overlap up to 93.75% for ultra-high spectral resolution. Hit HOLD to freeze any moment and study it at your own pace.

Dual 60-segment glass VU meters with peak hold indicators and live dB readouts show you exactly where your signal lives at all times. The full stereo intelligence suite includes a Stereo Image visualizer, L/R/Mid/Side spectrum display, and a live Phase Correlation Meter — mastering-engineer tools available on your Mac right now.

Works with any audio input your Mac supports. Switch sources instantly. Adjust input sensitivity from 0.1x to 4x. Fully customizable theme color. Settings persist between sessions. Open and go.

Built natively with SwiftUI using Apple's vDSP Accelerate framework. Not Electron. Not a web app. A real Mac app that launches instantly.
