Music / FXReal-Time Vocal Harmonizer
Sing one line and bring your own backup voices into the room.
Turn One Singer Into the Whole Chorus
Sing the hook alone and let the supporting voices arrive around you. Harmony works for karaoke nights, music streams, improvised Discord songs, character performances, and the moment a normal sentence suddenly becomes a choir.
Echo applies the harmony to your microphone live, so you can perform through Discord, OBS, streaming software, calls, and other voice apps without recording every backing part first.
Harmony Adds Voices—Auto-Tune Corrects Notes
A vocal harmonizer creates extra parts around your lead. Auto-Tune moves the lead itself toward notes in a chosen key. Use Harmony when you want a group; use Auto-Tune when you want the unmistakable tuned-vocal effect.
Start with a clear melody and listen back before the performance. The added voices follow what you sing, so steady notes and a comfortable range usually create a stronger chorus than forcing the biggest possible effect.
Under the hood
Turn one live vocal into a layered harmony effect for karaoke, music streams, Discord songs, hooks, and one-person-choir moments. Harmony follows your melody and adds supporting voices around it.
