Muzz vs Hear Through Walls

Muzz is a professional-grade real-time spectrum analyzer built for audio technicians, acoustic engineers, musicians, and sound enthusiasts. Whether you're diagnosing room acoustics, analyzing live microphone input, inspecting harmonics and feedback, or studying the frequency characteristics of any audio signal — Muzz gives you the tools to see exactly what you're hearing. 21 spectrum graph types, from standard linear analyzers to advanced harmonic alignment and octave-aligned displays, give you flexibility no single visualization tool can match. NEW IN 1.0.8 — Live frequency axis: Hz markers (100–8kHz) displayed permanently along the bottom of every visualization — Long press anywhere on the visualization to pin the exact frequency at that point for 2 seconds — Continuous background audio: Muzz now keeps analyzing when your screen locks or you switch apps — critical for live monitoring sessions — CarPlay compatible: enabling the microphone no longer interrupts audio playing through your car system — Frequency labels adapt automatically to dark and light mode Core Features — Load any audio file and visualize its full spectrum in real time — Live analysis mode via device microphone — ideal for room acoustics, stage monitoring, and field work — Persistent Hz frequency axis on every visualization — Long press to inspect exact frequencies at any point on the spectrum — Peak enhancer: isolates spectral lines (harmonics, fundamentals) and suppresses percussive noise — Toggle visualization variants to explore alternative display modes — Gain and treble controls to calibrate the display to your signal level — Dark and light mode with automatic label color adaptation — Runs continuously in the background — no interruptions during live sessions 21 Spectrum Graph Types Bars Extended Bars Short Line Spectrum Music Spectrum Linear OAS Overlapped Octaves Octave Aligned Spectrum Elliptical OAS Spiral OAS Harmonic Alignment TriOct Spectrum Overlapped Harmonics Harmonograph Cymbal Rainbow Spectrum Waterfall Rainbow OAS Rainbow Ellipse Spinning Ellipse Out of the Rabbit Hole Down the Rabbit Hole For in-depth theory on each spectrum type, tap the info icon to access the full Visualizations Guide.
