HALO

The vocal lands in tune — invisible or hard, your call.

What it's doing, then the same passage with HALO bypassed and in — level-matched, on its own faceplate — and the quick facts.

Why it exists

vocal pitch corrector

You know the night: the take is emotional, the pitch is almost there, and the tuner you own either lets flat notes slide or turns the performance into a robot. So you compromise — or you draw pitch curves by hand until 3 a.m.

HALO's YIN + phase-vocoder engine tracks the voice the way you would. Lock the key, set one retune knob: invisible at the bottom, full modern hard-tune at the top. Low male verse, high female belt, gliding runs — it holds.

In the session

  1. 01Lock key & scale once — every take after that lands in tune.
  2. 02Ease retune back for ballads that still read as human.
  3. 03Slam retune forward for the hard-tuned hook the artist asked for.
  4. 04Print with confidence — latency is reported, the drums stay tight.

Under the hood

What's inside HALO.

  • YIN + phase-vocoder tuning
  • Fast retune for hard-tuned vocals
  • Natural → full effect
  • Key & scale lock

Straight answers

Before you run HALO.

Which DAWs does HALO work in?

Pro Tools (AAX); Logic Pro and GarageBand (AU, macOS); Ableton Live, FL Studio, Cubase, Studio One and Reaper (VST3). It ships as VST3, AU, AAX on macOS and Windows. The install guide covers where each format lands and how to rescan if a host doesn't see it.

What are the system requirements?

macOS: macOS 11+ · Apple Silicon + Intel (Universal). Windows: Windows 10/11 · 64-bit · VST3 + AAX. Licensing is iLok; no USB dongle is required.

Does HALO add latency?

Where the engine needs lookahead or oversampling, HALO reports its latency to your DAW, which compensates automatically, so it stays in time with the rest of the session. On a live input, check your host's low-latency or monitoring mode.

Can I try HALO before buying?

Yes, through the subscription: the 7-day trial covers every unit, HALO included, with nothing charged until it ends. Individual plugins and bundles don't have separate trials.

Do I need an iLok dongle?

No. The license lives on your iLok account and can be activated to your computer, to iLok Cloud, or to a USB key — your choice.

How do I install it?

Through the Echelon Audio Hub: sign in once, and it installs, updates and rolls back every unit you own or subscribe to.

Are updates free?

Yes. A perpetual HALO license includes every update to HALO; subscribers get updates and every new unit as it lands.

What if it doesn't work for me?

Perpetual licenses have a 7-day refund window from purchase, as long as the license is surrendered from your iLok account. On the subscription, cancelling inside the trial means you pay nothing. If something is broken and support can't fix it, we'll make it right regardless.
