SoundKeys

Version 0.1.3 · Browser-based musical keyboard

SoundKeys is a high-definition, audio-reactive keyboard from CyprNet FunApps, a collection of browser-based experiences created by CyprNet Solutions LLC.

Explore detected musical notes from a microphone or a locally selected audio file, play the keyboard by touch or mouse, choose luminous colors, and record and replay the exact notes you perform on the keyboard.

Your audio stays in your browser. The note recorder stores only your actual on-screen or computer-keyboard key presses and releases, including timing, swipes, and chords. Microphone and file pitch detection only light up the keys and are not recorded. MIDI and JSON exports stay local.
