Audio Frequency Analyzer vs Muzz

"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone. With its simple operation, you can easily measure and evaluate your sound environment. This app measures the frequency response in 30 split band scale of 1/3 octave in real time. It can also display the FFT analysis results. It supports calibration for 1/3-octave bands. By adjusting the characteristics to match not only the built-in microphone but also your external microphone, it achieves high measurement accuracy. "Audio Frequency Analyzer" can be used for various applications, including sound room tuning, speaker settings, audio equipment testing, stage setup measurement, sound mixing environment evaluation and noise environment investigation. Features: - Frequency spectrum response measurement of 1/3 octave unit, 30 bands. (OCT) - FFT Analyzer (FFT) - Observation frequency range: 20 - 23000 Hz - Logarithmic amplitude display. - Touch-scroll function to adjust visible amplitude ranges. - Display the measured value of 1/3 oct bands at OCT mode. (dB@OCT) - Function to change the graph slope at FFT mode. (Slope): -3dB/oct (less than 1kHz), +3dB/oct (1kHz or higher) - Peak hold function. (Hold) - Average display function. (Avg): Time linear averaging. Fast-2.56sec, Slow-12.8 sec - Display response control. (Fast/Slow) - Reset of Measurement display position. (Scroll) - Snapshot of Measurement display. (Snap) - Calibration function in OCT mode. (Calibrate): 1/3 octave band offset and total offset setting. - Supports built-in microphone, headset microphone, and external digital audio connection. Note: The first time you access your microphone and photos after installing the app, the iOS system will ask you for permission to access them. If you have not enabled this setting, the app will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in the iOS setting "Settings > Privacy & Security > Photos or Microphone". Please visit our iOS app support page for more information about this app.

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.
