Clackalyzer vs Ripple Sound Meter

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.

Ripple Sound Meter turns your iPhone into a real-time sound toolbox: a decibel meter, a 3D scrolling spectrum, and a tuner, all running fully on your device. Instead of a plain flat dial, the spectrum is drawn as a live 3D sound-wave terrain and the dB reading drives a 3D needle gauge, so what you hear takes a shape you can watch. This app is for reference and curiosity only. It is not a certified measurement device; readings are uncalibrated estimates of ambient sound and should not be used for any professional or safety purpose. FEATURES - Decibel meter with a 3D needle gauge plus Max / Avg / Min hold - Live 3D spectrum terrain from real-time FFT, with an optional 2D bar view - Tuner that detects the main frequency, nearest note, and cents offset - Recording: capture a dB-over-time curve and replay it from a local list - A reference table of everyday sound levels (general knowledge, not medical advice) - A / C weighting, a calibration offset, and a dark instrument theme PRIVACY - Works entirely offline, with no account or sign-in - The microphone is used only to analyze sound levels live; no audio is recorded or uploaded - No data collected, no ads, and no in-app purchases
