What Is Stem Splitting?

Stem splitting (also called stem separation or source separation) is the process of taking a mixed song and isolating individual instruments into separate audio files called "stems." Each stem contains just one element — vocals, drums, bass, piano, or everything else.

Producers, DJs, and remix artists use stem splitting to create mashups, sample individual instruments, make karaoke tracks, practice along with isolated parts, or remix songs with full creative control. What used to require the original multi-track recordings can now be done with AI in seconds.

Our stem splitter uses two state-of-the-art AI models:

⚡
Mel-RoFormer — The current state-of-the-art for vocal isolation. Produces the cleanest vocal and instrumental separation available, with minimal artifacts and bleed.
🧠
Spleeter 2025 — Splits songs into 5 distinct stems: Vocals, Drums, Bass, Piano, and Other instruments. Powered by cloud GPU processing for fast, high-quality results.

What You Can Do With Stems

🎤 Create Acapellas

Extract clean vocals from any song for remixes, mashups, or vocal sampling.

🎹 Make Karaoke Tracks

Remove vocals and sing along to the instrumental of any song — perfect for practice or karaoke nights.

🎧 DJ Remixes & Mashups

Isolate drums, bass, or vocals from different songs and combine them into new mixes.

🎸 Practice & Transcription

Isolate a specific instrument to learn the part, or remove it to play along with the rest of the band.

🎬 Content Creation

Use isolated vocals or instrumentals for YouTube videos, TikTok content, podcasts, and more.

🔊 Sample Production

Pull individual drum hits, bass lines, or melodic elements to chop into new beats and productions.

Stem Splitter FAQ

Is this stem splitter really free?

▼

Yes, 100% free with no limits. No account needed, no watermarks, no hidden costs. Upload your song and download your stems — that's it.

What's the difference between 2-stem and 5-stem separation?

▼

2-stem mode gives you Vocals and Instrumental (everything else combined). 5-stem mode splits the song into Vocals, Drums, Bass, Piano, and Other — giving you more individual control over each element.

Is my audio data private?

▼

Your files are processed on secure cloud GPUs and immediately deleted after separation. We never store, share, or listen to your audio.

What audio formats are supported?

▼

Upload MP3, WAV, FLAC, M4A, or OGG files up to 50MB. All output stems are high-quality WAV files to preserve audio fidelity.

Can I use the stems commercially?

▼

The stems are yours to use however you want. Just be aware that if you upload a copyrighted song, the individual stems are still subject to the original song's copyright.

How does AI stem splitting actually work?

▼

Our AI models are trained on thousands of songs where the individual stems are known. The neural network learns to recognize the sonic characteristics of each instrument — the frequency patterns, timing, and spatial characteristics — and separates them from the mix. It's like having superhuman ears that can hear each instrument individually.
