Chord Freeze vs Microtonal Interval Eartrainer

You want something to solo over. Your options are a looper pedal you have to buy and carry, a backing track that locks you into someone else's key and tempo, or a second guitarist who is not currently in your living room. Chord Freeze is the fourth option. Play a chord. Tap Freeze. It holds — indefinitely, unchanging — while you play scales, modes, and leads on top of it. Tap again to release, and freeze a new chord. IT SOUNDS LIKE YOUR GUITAR Because it is your guitar. Chord Freeze captures the sound coming in and sustains that: your pickups, your amp, your pedals, your hands. It isn't a synth patch doing an impression of a guitar, and it isn't a sampled instrument. The chord you hear held is the chord you just played. Under the hood it's a granular engine rather than a looped buffer, which is why it doesn't tick, stutter, or breathe the way a short loop does. There's no seam to hear, however long you hold it. SIMPLE ENOUGH TO USE MID-PRACTICE One big button. Three knobs. Two switches. No menus, no presets, no project files. • DELAY — how long Auto-Freeze waits after your strum settles • WINDOW — how much of the chord it captures • VOLUME — the frozen chord's level against your live playing Freeze is retroactive: it grabs the sound that was already ringing just before you tapped, so you strum, let it settle, then tap. No countdown, no timing it perfectly. HANDS-FREE IF YOU WANT IT Turn on Auto-Freeze and it captures by itself once a chord has been sustaining — no reaching for the phone mid-exercise. Set DELAY to pick the moment it grabs, and keep both hands on the guitar. WORKS WITH WHAT YOU HAVE Plug in a USB or Lightning interface — iRig, Focusrite, anything class-compliant — and Chord Freeze switches to it automatically for a clean direct signal. No interface? The built-in mic works fine; just use headphones. TRY IT PROPERLY FIRST Twenty-five freezes, free, with nothing held back — the full app, not a limited demo. If you keep it, a one-time in-app purchase unlocks unlimited freezing forever. No subscription, no account, nothing to renew, no ads. Even after the trial, live monitoring, all the controls, and the help screen keep working. YOUR AUDIO STAYS ON YOUR DEVICE Chord Freeze processes everything locally. Nothing is recorded to disk, nothing is uploaded, and there is no analytics or tracking of any kind. The microphone is used to hear your guitar and nothing else. REQUIRES iPhone or iPad running iOS 17 or later. Headphones or an audio interface are strongly recommended — the built-in speaker and built-in mic together will feed back, so Chord Freeze mutes live monitoring automatically in that configuration.

Enjoying new exotic songs, but have no idea what their unfamiliar harmonies are doing? With a little training, you can recognize and reproduce crazy harmonies yourself! TRAIN YOUR EAR, TRAIN YOUR VOICE Interval Ear Trainer turns ratios from JI (just intonation) and EDO (equal divisions of the octave) into focused, colorful practice sessions. Choose prime limits from 5-limit (traditional Western harmony) through 7-limit, 11-limit, 13-limit, and higher. Then, identify the intervals you hear. Targeted practice brings back troublesome intervals with nearby contrasts and familiar landmarks. Once you've trained your ear, train your voice with Hum mode, and let the app detect how close you are to singing intervals. Or, get started on recognizing chords, scales, and even scale progressions! EXPLORE THE SPECTRUM Turn off the pressure and enter a free spectrum mode, where you can practice your chosen intonation at will. A live display shows where your voice lands and highlights nearby intervals. Turn real practice history into polished accomplishment cards and challenge your friends to see how they do. No user account, ads, or in-app purchases. Microphone audio is never recorded or uploaded. Game Center integration is optional.
