Read full description

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.

SpettroLive turns your iPhone into a real-time spectrum analyzer and helps you get rid of feedback, ringing and boomy sound in meetings, conferences, presentations and small events. LIVE ANALYZER - Spectrum from 20 Hz to 20 kHz on a logarithmic scale, updated in real time - Numbered peaks with frequency, level and musical note - The spectrum is split into zones: choose how many peaks to show and each zone displays its own, from lows to highs - Peak hold line with adjustable hold time from 0.5 to 5 seconds - Freeze the graph to read it calmly - Optimized for both portrait and landscape FIX AUDIO - Detects feedback and howling, room resonances and 50/60 Hz electrical hum - For each problem it suggests the cut in dB, the Q factor for a parametric EQ and the nearest band of a 31-band graphic EQ - Analyzes voice balance and flags boominess, muddy or harsh sound - 1/3-octave bars with the bands to fix highlighted - Share a report with the frequencies to fix GUIDED RING-OUT Slowly raise the microphone gain: SpettroLive records every frequency that starts to ring and tells you how to cut it on your mixer. Your system is ready in minutes. WHO IT'S FOR Sound engineers, speakers, teachers, event organizers, meeting rooms, churches, clubs and anyone using a microphone and speakers. PRIVACY Audio is analyzed on the device only: nothing is recorded or sent. Available in English, Italian and German. Note: levels are in dBFS and do not replace a calibrated sound level meter; suggestions are a guide and should always be checked by ear.
