What Is an Audio Splitter?

An audio splitter separates a song into its component layers — most commonly the vocal performance and the instrumental backing. Unlike our single-output Vocal Remover or Vocal Extractor tools, this one gives you both resulting tracks from a single upload.

It's the right choice when you genuinely need both files — for example, a karaoke backing track tonight and possibly an acapella for a remix later — instead of running two separate uploads through two separate tools.

What You Get

🎤 Vocal Track

The isolated singing, all instruments removed — an acapella.

🎵 Instrumental Track

The full song with vocals removed — a karaoke backing track.

Getting the Cleanest Split

Because Audio Splitter runs one separation pass and hands back both resulting layers, the same source-quality factors that affect any AI separation apply to both tracks at once:

Frequently Asked Questions

Is the audio splitter really free?
Yes, completely free. No trial period, no credit card, no catch.
How is this different from Vocal Remover or Vocal Extractor?
Vocal Remover gives you only the instrumental; Vocal Extractor gives you only the vocal. Audio Splitter runs the same AI separation but gives you both resulting tracks from one upload.
Will there be any bleed between the two tracks?
AI separation is very good but not perfect. Songs with clear vocal/instrument separation and minimal reverb produce the cleanest results. Complex arrangements may have some minor bleed in either direction.
What audio formats can I upload?
You can upload MP3, WAV, FLAC, M4A, AAC, OGG, AIFF, WMA, Opus, AMR, APE, WavPack (WV), and most other common audio formats. You can also upload video files (MP4, MOV, MKV, AVI, WebM, FLV, WMV, MPG, 3GP, and more) — we'll automatically extract the audio track. Maximum file size is 100 MB for audio, 1 GB for video.
What format are the output files?
Both tracks are delivered as high-quality MP3 files.
Do I get charged extra or wait longer for two files instead of one?
No extra charge — the tool is free either way. Generating a second output file adds only a few seconds compared to a single-output tool like Vocal Remover or Vocal Extractor, since both tracks come from the same separation pass.
I only ended up needing one of the two tracks — did I waste anything?
Not really — there's no file limit or quota to worry about, so downloading both and only using one costs you nothing beyond the file itself. If you already know for certain you'll only ever want one track, Vocal Remover or Vocal Extractor will get you a smaller, single-file download.
