Velvet Vocoder

VV17 turns your iPhone and iPad into a real-time vocal studio — auto-tune, harmony, and vocoder in one app. Sing or speak into your device and VV17 corrects your pitch to any key and scale as you go. Turn on harmony and it stacks up to four in-key voices under your lead, TC-Helicon style. Switch to Vocode mode and play a MIDI keyboard to drive the tuning by hand — your lead locks to the nearest held note while the others become live harmonies. FEATURES • Real-time auto-tune with adjustable correction amount and speed, from natural to hard-tuned • Automatic diatonic harmonies — stacked in-key thirds, 1 to 4 voices • Infinite mode swaps the harmony stack for a shimmering harmonic series • Vocode mode: control the tuner live from held MIDI notes • Classic vocoder / talkbox synth layer driven by your voice • Choose your key and scale, or explore just-intonation temperaments • Vocal FX: spread, humanize, sibilance, and response controls • Presets to get you started, including lush choir and modern hard-tune rigs • Works standalone or as an Audio Unit (AUv3) plugin inside GarageBand, AUM, Cubasis, and other hosts All processing happens on your device.
