Read full descriptionHide full description
Harmonizer - AUv3 is a real-time vocal harmonizer for iPhone and iPad. Sing into a microphone, select piano keys or chord pads, and hear live harmonies with low latency. Use it as a standalone instrument or load it as an AUv3 effect in compatible hosts such as GarageBand and Logic Pro for iPad. Key Features: - Live Vocal Harmonies: Process your voice in real time with harmonies based on held notes, piano keys, chord pads, or connected MIDI input. - Standalone and AUv3: Use Harmonizer as a standalone app or as an AUv3 audio effect in compatible music apps. Record the harmonized result directly in your host project. - Chord Pads: Play and hold chords with touch pads. Move between pads naturally, prepare the next chord while another is held, and use multiple octave ranges within each pad. - Audio Controls: Adjust dry vocal level, harmony level, output gain, and, in the standalone app, reverb amount and space preset. - Custom Chord Sets: Create, rename, duplicate, edit, and delete chord sets for different songs or performances. Choose the number of pads, chord roots, qualities, octaves, and pad layouts. - Piano Keyboard: Play with a multitouch piano keyboard designed for live performance. Choose Glide mode for sliding notes or Scroll mode to move across the keyboard while continuing to play. - iPad Dual Keyboard: On iPad, use two independent keyboard rows with separate positions for wider playing ranges. - MIDI Input: Use connected MIDI keyboards and controllers to play harmonies. MIDI works with chord pads and keys, including AUv3 host MIDI where supported. - MIDI Mapping: Map MIDI notes to chord pad positions and map MIDI knobs to key mixing controls such as Dry, Harmony, Reverb, and Output level. - Hand Control: Optionally control chord pads using the front camera. Hover over a pad with your hand and pinch to hold its chord. Includes a short tutorial plus low-light, no-hand, and multiple-hand guidance. - Local Processing: Microphone audio, camera input, chord sets, and performance settings stay on your device. Harmonizer does not upload or sell your audio or camera data. - Apple Intelligence Chord Progressions - Describe a mood, style, key, or progression idea to generate a named playable chord set with a short description; preview each chord, edit it, then save and use it live in Harmonizer. Requires a compatible device with Apple Intelligence enabled and availability may vary by language and region. Enjoy!

Verdict
The clearest difference is in-app purchases: Harmonizer at none against VocalRig Studio's 1. VocalRig Studio's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
