About soundtronics
soundtronics reconstructs microphone input in real time. Speak just a single word, and waves of sound begin to ripple outward. This isn’t a simple echo — it’s a live remix, a live rework.
What’s new
Version 1.2.0 · Updated October 11, 2026
- New: Cancel Own Sound. The app no longer re-records what it plays, so the clips fill with the sounds around you. Quiet sounds are also ignored while it is on. - New preset: Simple. - Tap the settings button again to close settings. The settings sheet remembers where you left off, and can be resized in finer steps. - Fixed icons that were missing on iOS 17.
