Vocal removers give you files — instrumentals, acapellas, drum stems. A music editor gives you an arrangement: levels, mutes, fades, and a single export you can practice to or upload.
Unmix Music Editor runs in the browser — import stems or full songs as layers, set regions, adjust levels, and export without installing a DAW. It is not a replacement for Pro Tools, but it covers a surprising amount of creator workflow between separation and publish.
This guide walks through post-separation arranging, mashup alignment, export tips, and when to graduate to a desktop DAW.
After separation, arrange
Separation is step one. Common step-two jobs in the editor:
- Line up vocals + new instrumental for mashups.
- Mute original drums stem while previewing your kit underneath.
- Join trimmed loops into a practice reel.
- Fade intros/outros for cleaner karaoke entries.
- Export a single mix for video editing apps.
Music Editor basics on Unmix
Open Editor and build a session.
- Import stems or full songs as layers.
- Set regions — trim within the timeline.
- Adjust levels so vocals sit above instrumentals.
- Mute/solo tracks to check bleed before export.
- Export WAV for production; MP3 for quick shares.
Mashup alignment workflow
Mashups live or die on timing and key.
- Analyze both sources with Key & BPM.
- Pitch shift one track if keys clash.
- Import stems into Editor — align downbeats visually.
- Nudge vocal phrases by milliseconds until grooves lock.
- Level-match — separated stems vary in loudness.
Practice loops and karaoke
Duplicate a chorus region to loop practice without re-processing the full song. Trim dead air with Cutter before importing — shorter layers are easier to manage.
Combine pitched instrumentals from Pitch with guide vocal recordings for before/after cover comparisons.
Export and handoff tips
Label exports descriptively: `artist-mashup-v3.wav`. Keep stem folders separate from mixed masters.
When handing off to video editors, export 48 kHz WAV if they specify; otherwise 44.1 kHz is standard for music.
Editor vs full DAW
The browser editor excels at quick arrangements and creators who live entirely online. Desktop DAWs add MIDI, VST plugins, automation lanes, and mixing buses for album work.
Many users separate on Unmix, arrange lightly in Editor, then import masters into a DAW for final polish — hybrid workflows are normal.
Common mistakes
Avoid these arrangement pitfalls.
- Clipping the master bus — pull stem faders down.
- Ignoring mono compatibility — check phone speaker playback.
- Desync after export — verify downbeat alignment before final bounce.
- Re-encoding stems repeatedly — keep WAV masters.
FAQ
Can I join MP3 files together online?
Yes. Unmix Music Editor lets you import multiple audio files, arrange them on a timeline, and export a combined mix — useful for stems, loops, and simple mashups without desktop software.
How do I mix vocal stems with a new beat in the browser?
Separate vocals with Unmix, analyze BPM/key, pitch-shift if needed, import vocal and instrumental layers into Editor, align timing, balance levels, and export.
Is an online music editor good enough for YouTube covers?
For level balancing, trims, and simple arrangements before video editing, yes. Final vocal production (comping, tuning, heavy FX) still benefits from a DAW — but many covers need only light arranging.
Should I arrange before or after vocal removal?
Remove vocals and split stems first, then arrange the resulting files. Arranging a full mix and then separating is slower and limits control.
What export format should I use from the editor?
WAV for video handoff, further DAW mixing, or archiving. MP3 for quick previews and messaging apps.
