Altitude

Vocal Performance Station

Unlock the potential in every voice

A vocal performance station for singers, producers, and live performers, Altitude takes real-time vocal processing to new heights – adding joy and creative exploration to your workflow. Pitch correction, smart three-voice harmonies, a MIDI-playable voice module, and deep modulation, all in real time with zero latency.

Dial in the classic hard-tune sound, or polish a take so cleanly no one knows it was touched. Build lush harmonies that follow your key automatically – on stage or in the studio. Play your voice like an instrument from a MIDI keyboard, or use your DAW's MIDI editor to arrange harmonies and melodies. Add depth and movement with modulation, from subtle pitch drift to textures that don't exist anywhere else.

Underneath it all is a pitch-correction engine that stands shoulder to shoulder with the industry's most respected names – precise, musical, and reliable. But Altitude was built to do far more than pitch correction alone, opening the door to entirely new harmonies and vocal soundscapes for studio productions and the live stage alike.

Whether you're singing for the first time or have spent years on stage, Altitude meets you where you are. Your new home for everything vocals.

Your voice is already something. Altitude helps you do more with it.

Natural by design

Built for the stage

Zero latency keeps everything tight in a live rig, the Play module lets you play your voice using a MIDI keyboard in real time, and MIDI scale control gives your lead and harmonies the possibility to follow chord changes automatically.

Altitude Lead module

Take the lead

The foundation of a pitch-effect is a solid pitch-correction module. With Altitude you get high-quality pitch-correction with formant-aware processing that’s quick and easy with no latency. Make your lead fatter with one of the two doubler-modes and the widener, or make a hard-hitting shift in the formants for effect.

Altitude Harmonies module

Live in perfect harmony

Up to three smart harmony voices that follow your lead in the right key, automatically avoiding unwanted dissonant intervals just like a human background singer. Each voice has its own vibrato, humanizer, and auto-formant correction. Doubler and widener blend them into any mix.

Altitude Play module

Play your voice like an instrument

Play and arrange your voice like an instrument - live from a MIDI keyboard or existing data in your DAW. Change the attack and release to set the vibe and control how everything fits in the mix with width, doubler and formant shifting (auto correction also available).

Altitude Modulation module

Modulation – from subtle to extreme

Bring rhythmic movement and evolving textures with subtle or extreme shifts in pitch, formants, harmony intervals, pan, volume and more. The modulation module gives you three independent modulators with up to 8 target parameters per modulator, each at it’s own rate or in sync with DAW. Pick a shape (sine / saw / square) or draw your own in the step-based editor with up to 16 steps.

Live mode

A dedicated zero-latency processing mode turns Altitude into a stage-ready solution.

Go beyond

Altitude opens up the voice as a sound design tool. Three independent modulators – each targeting up to eight parameters across pitch, formants, pan, volume, and more – micro tuning, and a preset library ranging from natural to otherworldly give you the building blocks for sounds that don't exist anywhere else.

We, the developers, made the tool we wanted to use ourselves. Working a lot with vocals, I was in need of a quality harmoniser and some tools for “crazy effects” to have fun with, on top of a great pitch correction tool. I wanted a good workflow, with all the functions but none of the fuss. And I’m happy that Altitude ended up giving all that for me!
