Stem Creator

Our stem creator divides your uploaded audio file into five dedicated tracks. You get an isolated vocal track and a combined instrumental track that merges the drums, bass, and other elements together. This is ideal if you need a clean acapella using our [acapella extractor](/acapella-extractor) or a backing track from an existing mix. The separation process preserves the clarity of the original recording so you can use the stems immediately.

Beyond just vocals and instrumentals, the stem creator pulls out the rhythm section. You receive separate files for the drums, the bassline, and a catch-all track for other elements like guitars, synths, or strings. This gives you the exact individual stems required to study a specific playing technique, sample a drum break, or remix the groove. Having these specific elements isolated makes reconstructing or modifying the original arrangement much easier.

You can test the stem creator without spending any money upfront. Every split generates a free 30-second preview of all five stems, starting at the 30-second mark of your uploaded song. If your song is under a minute long, the free preview starts right from the beginning. You can listen to the isolated vocals, drums, bass, and other instruments to verify the separation quality, and you only pay when you decide to download.

When you are ready to download your created stems, the stem creator provides professional audio formats. For a cost of 125 credits, which equals exactly $0.50, you get the complete song delivered as 16-bit, 44.1 kHz WAV files and 320 kbps MP3 files. These uncompressed WAV stems are ready to drop directly into your digital audio workstation for mixing, remixing, or sampling, ensuring your new project maintains excellent sound quality.

The stem creator runs on our own dedicated servers using the Demucs htdemucs open-source model developed by Meta AI research. This specific setup means your audio is processed very quickly. You will usually hear your 30-second preview in about one minute. If you are processing a standard four-minute song, the track is fully split into all five stems in approximately three minutes, so you never have to wait long for your files.

You can upload MP3, WAV, FLAC, M4A/AAC, or OGG files up to 90 MB and 10 minutes long to the stem creator. Splitting is free for one song a day without an account, or five songs a day when signed in. To download, a simple one-time $5 purchase via FloatPass adds 1,250 credits to your balance, which is enough to download 10 full songs. There are no subscriptions to worry about.

Electronic music producers use a stem creator to sample parts of an existing track. By isolating the vocals or a specific drum break, they can build an entirely new beat around the original performance. The downloaded WAV files drop right into their software, allowing them to publish unofficial remixes or mashups online.

Bassists and drummers use the stem creator to learn complex parts by ear. By isolating the bass or drum stem, they can hear every nuance of the original performance without the guitars or vocals getting in the way. They take the isolated MP3 to their practice room to master the exact technique.

Singers use the stem creator as an [instrumental maker](/instrumental-maker) to practice their vocal routines. They upload a finished mix, let the AI remove the original singer, and download the combined instrumental stem. They then use this custom backing track to perform live at local venues or record their own cover versions.

Club DJs use the stem creator to separate tracks and build custom intro edits for their live sets. By extracting the acapella with our [vocal remover](/vocal-remover) or isolating the drum stem, they can blend two different songs together smoothly. They load the separated stems onto their DJ controllers for live mixing.

Video editors use the stem creator to salvage messy audio recordings. If a piece of background music has distracting vocals, they can split the file and use only the instrumental or drum stems beneath their voiceover. The 16-bit WAV downloads ensure the background audio remains crisp and professional in the final video export.
