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.

Does not continuously run on iOS. Does not show frequencies. Just a pretty display. **Developer response:** Thanks for the honest feedback — we hear you. We’re happy to let you know that the latest version of Muzz addresses every point you raised: 1. Live sound: real-time audio processing is now fully supported. 2. Continuous background running: the app now stays active on iOS without interruption 3. Frequency display: a full spectrum/frequency view has been added We’d love for you to give it another try and update your review. If you run into anything, reach out to us directly through the app — we’re committed to making Muzz the best audio spectrum tool on iOS. ### 1/5 — pointless *2025-02-26* what good is a bar graph with out labels? I have no clue the db. range nor the frequincies that are displayed... how can i analyze anything if i dont know what im looking at. Yes there is a brief discription in the info section 32h to 8k so i have to figure out the freq layout to scale, serioulsy! Pointless without db levels and the frequencies labeled across the bottom. and side like a normal graph. I would like a refund. ### 1/5 — Microphone doesn’t work when using car play *2024-02-15* Is there a way to allow the sound to be analyzed while using car play? It just pauses the sound when the microphone is unmuted. **Developer response:** Fixed in version 1.0.7 which is released soon. The issue was that activating the microphone was taking exclusive control of the audio session and cutting off CarPlay. We've updated the audio session to use mix mode, so CarPlay keeps playing while the mic captures and analyzes the live sound simultaneously. Give it a try on your next drive. ### 1/5 — Laggy. *2024-01-27* I was hoping this was going to be like the visualizer that came with Windows Media Player back in the day, but It's doesn't respond to the music like you'd expect. The app itself also keeps freezing and I have to restart it to get it to play anything. Dont waste your time or money ### 1/5 — app is junk *2023-07-01* Can't actually use app because nothing is labelled ### 5/5 — BIG Help! *2023-03-27* Thank you so much for the development of this app. I purchased this app to assess the quality of my 🎶 files used for djing Conscious Dances, in the San Francisco Bay Area. I started out years ago with lots of MP3's but have since been buying higher quality files. It’s been super helpful to sort out the good the bad and the ugly songs in terms of their qualtiy, etc. ;o). This app would be far more useful if the song scroll slider could be manually moved (like in all music players, etc.). Sometimes I need to skip to the more firey part of the song for assessment, for example. Thank you for considering this request! ### 4/5 — Works well *2022-12-24* This app works well on my MacMini M1 2020, OS Ventura 13.1. It would be more useful if musical note names with octave numbers (e.g. C1 etc to B8) were displayed on x-axis on more spectrum views, and perhaps also an indication of units on y-axis. ## Frequently asked questions about Muzz ### What is Muzz used for?
