Live Vocal Harmonizer
Evocal is the flagship harmonizer demo: real-time pitch tracking, chord-aware voicings, and a full performance surface (pads, arp, drums, notation). Microphone access is required — launch in a new tab for the best experience.
The Csound vocal harmonizer also lives inside Band Studio (amber section). Evocal on demo.thiri.ai uses Web Audio + YIN pitch detection for live performance.
