InTune-Harmony

InTune-Harmony by Antelope Audio is a vocal harmony generator plugin that adds 2, 3, or 4 harmony voices to a lead vocal in real time. Choose your key and scale, then use the InTune button for pitch correction based on the same algorithm found in Antelope’s Performer and Chorus plugins. The Space control spreads the generated voices across the stereo field, while the Color control shifts timbre from Neutral to Deep, letting you shape the blend between the lowest and highest harmonies. It excels at creating realistic backing vocals and automatic double-tracking to beef up choruses with epic, impactful width. The intuitive interface keeps workflow fast, and because it runs natively on Mac or PC, it works with any interface and DAW—no extra hardware required. Ideal for hobby producers and songwriters in FL Studio, Ableton, or Logic who want lush vocal stacks without hiring session singers.
