# X-Ray

> Drop in a reference track and find the sounds in your own library that match it — as a whole, or split into stems

## Overview

X-Ray turns a track you like into a way to search your own library. Drop in any track, loop, or sample, select the part that caught your ear, and X-Ray finds the closest sounds you already own. It's search by reference: instead of describing a sound in words, you point at one.

It runs on your machine. The reference never leaves it, and nothing is uploaded.

## Opening X-Ray

Open X-Ray as a panel, or right-click any sample and choose **Open in X-Ray**. It accepts common audio files — WAV, MP3, AIFF, and FLAC — so a bounce, a loop, or a favourite record all work as a reference.

## Matching against your library

Select any region of the reference and X-Ray ranks the sounds in your library by how closely they match it. From there you can:

* Play back and compare matches against the region you selected.
* Save a matched region into your library as a new **X-Ray Captures** source.
* Copy a match to the clipboard, or drag it straight into your DAW.

## Stem splitting

Baseline X-Ray matches the reference as a whole. Stem splitting takes it further: it pulls the reference apart into **vocals, drums, bass, and everything else**, so you can match each part on its own. Drag a region on any stem lane and X-Ray searches just that part of the mix — a drum lane finds your drums instead of the whole track at once.

Separation runs on your machine like the rest of X-Ray. The first time you split a track, a one-time model file downloads; after that it works offline.

<Note>
  Baseline X-Ray — dropping in a reference and matching the whole mix — is free
  on every plan. Stem splitting is part of the paid plans. See
  [Plans & Usage](/reference/plans-usage) for what each plan includes.
