What Altitude does
The core is a pitch-correction engine that the developer describes as fast, formant-aware and free of latency. Correction is meant to sound natural even at extreme settings, and the processing sits alongside established vocal tuners in precision.
Beyond correction, Altitude builds harmonies. Up to three smart voices follow the lead line in the correct key, automatically skipping dissonant notes, and each voice is processed on its own. A MIDI-controllable scale system sets the key, and the voice module can be played from a keyboard like an instrument. Two doubler modes and a built-in widener thicken the lead, and a shift formants control changes the tonal character.
Modulation is handled by three modulators, each able to reach up to eight targets, with DAW-synced free-running rates. A 16-step modulation envelope editor offers optional smoothing, and vibrato can be shaped with a natural fade-in whose rate and depth vary per voice.
Altitude is distributed in cracked and pirated form through the usual channels, so searches for an Altitude crack, a working serial key or a keygen tend to point to torrent and magnet link releases. The Windows build is passed around as x64 crack and x86 crack, the macOS build as a .dmg crack, and repacks often arrive packed as .rar or .iso. Queries pair the name with patched, activator and free full version, and the VST2, AU and AAX builds are shared as VST crack, AU crack and AAX crack.
Key features
- Formant-aware pitch correction. The correction engine works on pitch while preserving formants, and the developer lists it as having no latency.
- Doubler and widener. Two doubler modes and a built-in widener fatten the lead, with individual mix levels for each stage.
- Punch-in selective correction. Punch-in mode restricts correction to selected passages instead of processing the full track.
- Three-voice smart harmonies. Three harmony voices follow the lead in the detected key and skip dissonant notes, each processed individually.
- Modulation and envelope editor. Three modulators with up to eight targets each are driven by a 16-step envelope editor with optional smoothing, synced to the DAW.
Compatibility
Altitude is distributed as VST2, AU and AAX for Windows 10 and macOS 10.13 in 64-bit builds, with native Apple Silicon support listed.
Who it is for
Vocalists, vocal producers and mix engineers who want pitch correction, harmony generation and vocal doubling in a single plugin, and performers who want to play harmonies from a MIDI controller.
