How to use Oxide in FL Studio

By Will Barratt, who builds Oxide · Updated 8 November 2026

Short answer: route each stem to its own mixer track, put Oxide in the first effects slot, run a scan, listen to what was removed, then render before compression.

FL Studio is a common Windows setup for people mixing AI stems. The snag is usually the file, not the playlist: a Suno vocal or hat stem sounds harsh, and then Fruity compressor or a third-party saturator makes the top end worse.

This guide is the FL Studio workflow: get each stem onto its own mixer track, add Oxide as a VST3 or CLAP effect, inspect it, then mix. Plugins are in beta; if Oxide does not appear in the plugin database, use the standalone Oxide app and drop the cleaned WAV into the playlist.

For install basics, see How to set up Oxide in your DAW. For what to listen for, see How to clean Suno stems.

Get stems into the playlist and mixer

1. Drop each stem on its own playlist track.
2. Route each one to its own mixer track. Do not stack every stem on the same insert if you want to inspect them separately.
3. Line the clips up at the same start point. Avoid stretching a stem just to make it fit unless you mean to change timing.
4. Name the mixer tracks so you can solo a vocal or drum part quickly.

If another instrument leaks into the gaps, that is a separation problem. Cleanup will not complete the split.

Add Oxide on a mixer slot

1. Download the Windows installer from oxide.battleship.me. If Windows SmartScreen appears, click More info, then Run anyway.
2. In FL Studio, open the Plugin database or Plugin Manager and rescan if Oxide is missing.
3. On the stem’s mixer track, add Oxide in an effects slot — VST3 or CLAP.
4. Put it before compressors, saturators, and de-essers on that mixer track.

If the wrapper asks you to pick a format, choose the 64-bit VST3 that matches your FL Studio installation.

Inspect and clean

1. Solo the mixer track and listen.
2. Run a scan.
3. Listen to what was removed. You want fizz and metallic residue, not the body of the part.
4. When you are happy, render the mixer track or replace the playlist clip with a cleaned WAV from the Oxide app (WAV export is part of Pro), so later effects hear the cleaned stem.
5. Then mix as usual in FL Studio.

Compare at matched loudness. You do not need to process every stem in the project.

Batch Triage in Lite checks up to 3 stems; batch folder render is part of Pro. Oxide Pro and Oxide Studio unlock 24-bit WAV export, the 5-band breakdown, and folder rendering.

Common questions

Where do I put Oxide in FL Studio?

On the mixer track for that stem, in an effects slot, before compression.

Oxide is not in the plugin database.

Rescan plugins, confirm you installed the 64-bit Windows version, or clean the file in the Oxide app and import it. Plugins are in beta.

Can I clean a folder of stems first?

Yes. The standalone app can inspect a folder; Pro and Studio can render the cleaned WAVs, which you then drop into the playlist.

Which stems should I clean first?

Usually the vocal and the hats or cymbals. Bass and kick rarely need anything. Clean the parts that bother you and leave the rest.
