Installation instructions, system requirements and AutoPitch settings. For account or plugin issues, contact hello@sparkaudio.org.
Install on Windows
Each Spark installer puts its VST3 plugin where your DAW can find it. You can also install the optional standalone app.
-
Download your plugin
Sign in to your Spark Audio account, verify your email and choose the Windows download for your plugin. Save the .exe installer to your computer. Downloading does not start your trial.
-
Close your DAW and run the installer
Save your session and close your DAW before installing or updating. Run the downloaded installer and choose whether to include the standalone app.
-
Follow the setup steps
Each installer puts its plugin in the standard VST3 folder automatically:
C:\Program Files\Common Files\VST3Windows asks for administrator permission to install into Program Files. You do not need to move or extract any plugin files yourself.
-
Rescan plugins in your DAW
Open your DAW’s plugin manager and run a rescan, or restart the DAW. Load your installed Spark plugin as an audio effect. Each product has its own installer and activation.
-
Activate your plugin
Choose Activate in your plugin, or open its Account control. Your browser opens so you can sign in and approve your computer. Return to the plugin when connected. If eligible, your 30-day trial begins when activation completes. The optional standalone app uses the same activation.
Updating later? Save your session, close your DAW and run the latest installer from your account. Your presets and activation are preserved.

AutoPitch settings
The new AutoPitch interface brings the pitch monitor, Retune speed, Correction and Humanize together. Key, Scale, Formants, Vocal range, Channel mode and the target-note keyboard remain available on both pages. Open Detailed tuning at the top right for the additional tuning controls, and choose Back to AutoPitch to return. To compare with the untouched vocal, bypass AutoPitch in your DAW.
Set the key and scale
The default, Chromatic, pulls each note to the nearest of all twelve. That’s safe, but a note sung halfway between two can land on the wrong one. If the song is in A minor, choose Key A and Scale Minor, and AutoPitch only aims for those seven notes.
There are also Major, Major and Minor pentatonic, Blues, Dorian, Phrygian, Mixolydian, Whole Tone and Diminished. For anything else, click notes in the Target notes strip in Detailed tuning to build a Custom scale.
Choose the vocal range
In Detailed tuning, set Vocal range to Bass, Baritone, Tenor, Alto, Mezzo soprano or Soprano to match the singer. Matching the range helps the pitch detector. Full range, the default, covers the widest range.
Natural pitch correction
- Hard tune 0%
- Retune speed 35 ms
- Correction 85%
Start here for a lead vocal that drifts flat on long notes. With Hard tune lowered, lower Retune speed values react faster. Raise Humanize to keep more of the singer’s vibrato and inflection: it lets the voice move around each note while still correcting the note’s centre.
The hard-tuned effect
- Hard tune 100%
- Correction 100%
New instances start with Hard tune at 0%. For this effect, open Detailed tuning and set Hard tune to 100%, then go back to the main page and set Correction to 100%. Setting Retune speed to 0 ms on its own won’t get you there.
At 100%, Hard tune overrides Retune speed, Humanize, Note transition, Tolerance and Note hold. You can see it in the window: Set by Hard tune appears under Retune speed and Humanize, and the footer reads Hard tune. Choose the key and scale first: in Chromatic every note is a target, including the ones that aren’t in the song.
Formants: Preserve or Shift
Preserve is the default for new instances from version 0.1.37. It keeps the voice’s formants where they are while the pitch moves. Shift lets the formants move with the pitch. Existing projects keep their saved setting.
Switching to Preserve takes about a tenth of a second, ending in a short crossfade, so loop a phrase, try both, and keep whichever sounds more like the singer.
Mono vocal is the default
New instances average left and right into one centred voice before tuning, without a jump in level. That suits a vocal recorded with one microphone.
To keep a stereo recording’s width, choose Stereo under Channel mode in Detailed tuning. The footer of the window shows Mono or Stereo, so you can check at a glance. With Correction at 0% and Output at 0 dB, or with the plugin bypassed in your DAW, the original stereo signal passes through untouched.
Match the tuning reference
If the track wasn’t recorded at A4 = 440 Hz, set Tuning reference in Detailed tuning to match it. It goes from 415 to 466 Hz.
Adjusting controls
Drag a knob, use the mouse wheel or the arrow keys, double-click to reset it, or click the value and type an exact number. The window resizes too, if you want the controls bigger.
Common questions
Is there a Mac version?
Not yet. Spark plugins run on Windows 10 and 11, 64-bit. When a Mac version is ready, this page will say so first.
Which plugin formats do you support?
VST3, 64-bit, on Windows. AutoPitch also comes as a standalone app, which is handy for trying settings on a microphone without opening your DAW.
Will it work in my DAW?
Spark plugins are standard 64-bit VST3s, so any Windows DAW that loads VST3 should load them. We’re still testing in specific hosts. If something misbehaves, email us with the details listed below and we’ll look into it.
How does the free trial work?
Each of the eighteen plugins has its own 30-day free trial, starting when you activate that plugin. One trial per product, account and device. Downloading does not start a trial. No card required. Trials do not renew or charge you automatically.
What’s in Spark Complete?
Spark Complete includes AutoPitch, Compressor, Limiter, Doubler, EQ, Delay, Reverb, DeEsser, Gate, Air, Saturator, Rider and Clamp for €27.99 as a one-time purchase. Future plugins are not included. Existing single-plugin licenses are not deducted from the bundle price. Every plugin also has a separate 30-day trial. See all prices.
How do updates work?
Save your session and close your DAW, then download and run the latest installer from your account. Your presets, activation and saved session settings are preserved.
To hear when an update ships, email hello@sparkaudio.org and ask to be told about releases. You’ll get one short email per release and nothing else.
How do licensing and activation work?
Create an account and verify your email, then follow the activation instructions in your account. AutoPitch’s free trial lasts 30 days from first plugin activation. Each account and device can receive only one trial; reinstalling or creating another account does not restart it. Trials never renew or charge automatically.
Can I use AutoPitch live?
It’s built for mixing. AutoPitch reports its latency to your DAW, so playback lines up, but you’ll hear roughly 50 ms or more of delay when monitoring through it, depending on sample rate.
What settings does a new AutoPitch instance use?
AutoPitch defaults to Hard tune 0% and Correction 100%, with Retune speed at 5 ms and Humanize at 0%. Saved projects keep their stored settings. For a subtler effect, try the settings under Natural pitch correction.
