frequently asked questions
Stem separation, answered.
How it works, what it costs (nothing), and what happens to your files.
Product
- What is ytstems?
- ytstems is a browser-based audio tool that splits a song into separate stems such as vocals, drums, bass, guitar, piano, other, and instrumental. Paste a YouTube link to start, or upload your own audio file.
- How do I split a YouTube song into stems?
- Paste the YouTube link on the homepage, pick a separation model, and start the job. When it finishes, the isolated tracks open in the in-browser mixer where you can solo, mute, balance, and download them.
- Can I use ytstems without installing software?
- Yes. Paste a public YouTube link or upload a supported audio file, then preview, mix, and download results in a modern desktop or mobile browser.
- How do I remove vocals from a track?
- Separate the song, then mute the vocal lane to make an instrumental or solo the vocal lane to hear and download the acapella.
Formats and quality
- Which audio formats does ytstems support?
- Uploads support MP3, WAV, FLAC, AAC, OGG, AIFF, WMA, Opus, AU, APE, and M4A. Available downloads include MP3, WAV, FLAC, OGG, AAC, Opus, and AIFF.
- Which stems can it separate?
- Common outputs include vocals, drums, bass, guitar, piano, other, and instrumental. Exact outputs depend on the selected model and source audio.
- Will every separated stem sound clean?
- Quality varies with arrangement, recording, compression, source quality, and model choice. Dense mixes and overlapping instruments can leave audible bleed or artifacts, so preview results before downloading.
Limits and donations
- How much does ytstems cost?
- Nothing. ytstems is free to use and funded entirely by donations — there are no paid tiers, subscriptions, trials, or cards. Guests get 5 separations a month per network; creating a free account adds 5 bonus separations for a total of 10. Saved mixes: up to 40 per account.Support ytstems
- How do I get more separations?
- Create a free account to add 5 account separations each month on top of the guest allowance (10 total instead of 5). Your balance resets at the start of each month. There is nothing to buy.
- How can I support ytstems?
- ytstems stays free because people donate. If the tool helps your work, you can send a donation to the addresses shown on the donate page: an EVM address that accepts assets on any EVM chain, and a Solana address for SOL and SPL tokens. Donations keep the service free for everyone.EVM chains

- A submitted track can be up to 15 minutes long.
- How long does separation take?
- Processing time depends on track length, selected model, source preparation, and available compute. The on-page progress log reports real stages instead of promising a fixed completion time.
- Can I run more than one separation?
- You can submit work from another tab, but jobs may briefly wait when available processing capacity is busy. There are no paid tiers and no priority processing — everyone gets the same fair access.
Privacy and accounts
- What happens to guest files?
- Guest uploads and stems use temporary storage for processing and playback. Guest stems normally expire about one hour after processing, with automated cleanup handling temporary files that remain longer.
- What changes when I create an account?
- An account can save completed mixes in protected storage and create durable Share mix links. Saved audio remains available until it is removed or a deletion request is completed.
- May I upload any song?
- Only upload audio you own or are authorized to process. You remain responsible for copyright, licensing, privacy, and any use of separated outputs.
- What happens if processing fails?
- The interface reports the failure and stops the job. A failed run should not be treated as a completed separation; contact support if your displayed balance appears incorrect.
- How can I ask about my data or account?
- Email help@ytstems.xyz with the account email and request details. Do not send passwords or private audio attachments by email.
