Sounn VR Audio Analyzer

Analyze rooms, speakers, and live spaces with real-time FFT/RTA, spectrograph history, VR overlay, signal generator, presets, compare, and export.

Sounn VR turns your iPhone or iPad into a real-time audio analyzer for rooms, speakers, studios, stages, and live spaces.

See sound as it happens with live FFT and RTA views, spectrograph history, and a camera-based VR overlay that places spectrum analysis over the space you are checking. Use it for fast setup checks, speaker tests, room comparisons, feedback hunting, education, and repeatable audio workflows in the field.

REAL-TIME AUDIO ANALYSIS

• Live microphone spectrum analysis from 20 Hz to 20 kHz.
• RTA bar, line, and Bar+FFT display modes.
• Linear, log, octave, 1/3, 1/6, 1/12, 1/24, and 1/48 octave analysis.
• Selectable FFT sizes: 1024, 2048, 4096, and 8192.
• Multiple FFT windows including Hann, Hamming, Blackman, Blackman-Harris, Flat Top, and Rectangular.
• Peak hold, decay controls, reference snapshots, and difference views.

SPECTROGRAPH HISTORY

• Watch frequency energy change over time.
• Review recent live sound events with an in-memory history.
• Use horizontal or vertical spectrograph direction for different workflows.

VR AUDIO OVERLAY

• View the live spectrum over the camera feed.
• Quickly connect what you hear with where you are in the room.
• Record walkthroughs with the spectrum overlay and save them to Photos with Sounn Pro.

BUILT-IN SIGNAL GENERATOR

• Generate sine waves, pink noise, white noise, and swept sine.
• Set frequency from 20 Hz to 20 kHz with a log slider and numeric control.
• Run generator and analyzer together for loopback-style setup checks.

SAVE, COMPARE, AND EXPORT WITH SOUNN PRO

• Save and recall analyzer presets.
• Compare live measurements against saved references.
• Export CSV data, spectrum images, spectrographs, and settings files.
• Share results through Files, Photos, Clipboard, Mail, AirDrop, and the iOS Share Sheet.
• Back up settings and preset definitions with iCloud.

LOCAL BY DESIGN

Sounn VR processes audio on your device. Measurements and presets stay local unless you choose to export or back them up.

Sounn VR is built for practical visual audio analysis. It is not a certified SPL meter, medical hearing test, or safety dosimeter.
