Sounn VR Audio Analyzer vs Clackalyzer

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. Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Clackalyzer lets you build a personal library of keyboard sessions — each one a complete snapshot of a build at a moment in time. Audio recording, build photo, spectrum snapshots, notes, and ratings, all in one place. Over time your library becomes something valuable: a history of every board you've owned, every mod you've tried, every switch you've tested. You can go back, compare, share, and actually remember what that build sounded like six months ago. **Each session captures:** • A WAV audio recording • A build photo • Full build metadata — board, plate, switch, foams, mic distance • Spectrum snapshots and spectral profile from the live analyzer • Ratings across five categories: Sound, Feel, Build Quality, Customization, and Value **Free recording modes** Four guided session types are provided: Comparison, Solo Switch, Typing Test, and Freestyle. Each one walks you through setup with a placement tip and best-practice checklist, counts you down from three, and auto-finishes when the session is done. **Your library** Browse every session with waveform previews, key build photos, acoustical metrics, and ratings at a glance. Tap any session for full playback, spectral profile, band energy breakdown, and complete build metadata. Save comparisons to revisit anytime. **The tools** A real-time FFT spectrum analyzer runs while you record — log-scale frequency display from 20 Hz to 20 kHz, peak hold, EMA average, cursor readout, and up to 6 labelled spectral peaks. **Clackalyzer Pro — $9.99, one-time unlock, no subscription** • Compare — record with Comparison Mode (Gentle, Normal, Hard, Rapid, and Typing Test steps timed to a metronome), then compare any two sessions side by side with A/B audio playback, spectrum overlay, band energy breakdown, and a plain-English summary of every sonic difference. Save comparisons and export to PDF. • Export & Share — share sessions as WAV or M4A for use in any DAW or audio tool • Frequency Filter — cut low rumble or high hiss to zero in on your switch's true sound • Noise Calibration — remove room noise so more of your keyboard's sound comes through • Waterfall Spectrogram — real-time scrolling spectrogram view • FFT size control — fine-tune frequency resolution • Three additional exclusive themes based on popular keycap sets; Metro-ish, Beige and Neon... (Kudo's to Nephock at NK!) **Themes** Five themes modeled after popular keycap sets. Default and Light are free — Metro-ish, Beige, and Neon unlock with Pro.
