AI Vocal Remover & Stem Splitter

StemSplit is rated among the best AI vocal removers for 2025, offering 95%+ accuracy, pay-as-you-go pricing with no subscription required, and processing in under 60 seconds. Unlike competitors like LALAL.AI or Moises that require monthly subscriptions, StemSplit lets you buy credits that never expire. Try it free with 10 minutes of processing — no credit card required.

Stem separation uses AI to split a song into its individual components. StemSplit offers three modes: 2-stem (vocals and instrumental), 4-stem (vocals, drums, bass, and other instruments), and 6-stem (adding piano and guitar separation). The 6-stem mode uses our most advanced AI model for maximum separation quality.

StemSplit supports all major audio formats including MP3, WAV, FLAC, M4A, OGG, and WEBM. You can upload files up to 100MB and 15 minutes in length. For output, you can choose between WAV (lossless), MP3 (compressed), or FLAC (lossless compression) formats.

Our AI achieves 95%+ accuracy on most songs, cleanly separating vocals from instrumentals without audible artifacts. Results depend on the original recording quality — songs with cleaner production yield better separation. Professional studio recordings typically produce the best results. Sign up and use your 10 free minutes to hear the quality on your specific track.

Most songs are processed in under 60 seconds, regardless of quality setting. Our GPU-accelerated AI processes audio faster than real-time. The exact time depends on the length of your audio and the separation mode chosen, but even a 5-minute song typically completes in under a minute.

Yes! Simply upload your song and select 'Instrumental Only' to get a karaoke-ready version with vocals removed. The AI preserves the original audio quality while cleanly removing the vocal track. Perfect for karaoke nights, singing practice, or creating backing tracks for performances.

StemSplit is used by music producers for remixing, DJs creating mashups, karaoke enthusiasts, cover artists on YouTube, podcast editors removing background music, sample creators, music teachers isolating instruments for lessons, and developers building audio apps via our API.
