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. — FEATURE HIGHLIGHTS — • Real-time FFT spectrum analyzer — 64 to 32,768 FFT size • Bars and Line visualization modes with smooth animation • Logarithmic and Linear frequency scaling • 16 / 32 / 64 / 128 frequency bands • System audio loopback — no virtual driver needed (ScreenCaptureKit) • Microphone & audio interface input with source selector • Stereo VU meters (L/R) with peak hold • Stereo Image visualizer • Mid/Side (M/S) spectrum analysis • Phase Correlation meter for mono compatibility • Sensitivity (gain) rotary control • Overlap control 25%–93.75% for temporal resolution • HOLD mode — freeze and inspect any frame • 7 premium accent color themes • Settings persist between sessions

OmniRTA

Read full description

OmniRTA is an advanced real-time acoustic analyzer engineered for audio professionals, sound design students, musicians, and acousticians. Combining high-performance DSP with a clear, pedagogical interface, OmniRTA bridges the gap between signal theory and practical sound analysis. A Unique Educational & Comparative Platform: Unlike traditional RTAs limited to a single processing method, OmniRTA integrates multiple frequency analysis engines, allowing you to compare signal behaviors side by side and understand how different algorithms handle transient vs. steady-state audio: Standard Direct FFT: High-speed frequency decomposition optimized for real-time responsiveness, wideband signals, and general monitoring. Constant-Q / Fractional Octave Filterbank: Acoustically relevant octave and fractional-octave banding (1/1, 1/3, 1/6, 1/12, 1/24 octave) that matches human auditory perception across the audible spectrum. Proprietary Low-Frequency Transient Engine (Exclusive): Traditional FFT algorithms suffer from a strict time-frequency uncertainty trade-off, either sacrificing time accuracy or frequency resolution in the low end. OmniRTA introduces an innovative analysis engine specifically designed for low-frequency transient and percussive content. Accurately track fast double-kick drums, heavy techno sub-bass patterns, and low-end impact dynamics with surgical frequency definition and zero temporal smearing. Key Features: • Real-time multi-algorithm spectrum visualization. • Standard acoustic weightings: A, C, and Z (Flat). • Response ballistics: Fast, Slow, Peak Hold, and Infinite Peak. • Native high-performance DSP core written in Rust for minimal latency and optimal battery efficiency. • Seamless cross-platform experience across iOS, iPadOS, and macOS. Free vs Pro Version: OmniRTA offers essential spectrum analysis features for everyday work and learning. Upgrade to OmniRTA Pro via a one-time in-app purchase to unlock advanced fractional octave bands, deep algorithm customization, and extended logging tools.

Verdict

The call

The clearest difference is in-app purchases: SoundScope at none against OmniRTA's 1. OmniRTA's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 26.1). On price and ads there is nothing between them.
