milliVerb turns your iPhone or iPad into a real-time reverb instrument for voice, instruments, and other live sound. Shape the effect as you play with hands-on controls designed for performance. • Build a space with expressive reverb and modulation controls. • Shape tone with a visual EQ, including filters and adjustable bands. • Tune low-, mid-, and high-frequency decay independently. • Use adaptive feedback EQ to reduce persistent resonances. Feedback depends on the room, speakers, microphone, and volume; protection cannot guarantee that feedback will never occur. • Record a dry take on demand, then audition it with reverb and adjust the mix. milliVerb’s live processing, recording, playback, and factory presets are free to use without a session timer. milliVerb Full is an optional one-time purchase that unlocks dry WAV saving, processed-mix export, and custom presets, favorites, and performance sets. Restore a previous purchase in Settings. Recording starts only when you tap Record. Takes are stored in the on-device Recordings library. Exporting or sharing is initiated by you.
