Contact us
VocaSplitter is a small independent project, so email is the only channel — but it is read by the person who builds the thing, and you will get a real answer.
We aim to reply within two to three working days. There is no phone line and no live chat.
A file will not separate
Before emailing, two things fix the large majority of failures: re-export the file as a 44.1 kHz WAV, and check that it plays end to end in a normal media player. Most rejections come from a damaged container or an interrupted download rather than the tool.
If it still fails, send us:
- The file format, approximate length and file size.
- Which separation mode you selected.
- What you saw — an error message, an endless processing screen, or stems that came back silent.
- Your browser and operating system, and whether you tried a second time.
Please do not attach copyrighted audio. A description is enough for us to reproduce most problems.
The stems came back but sound wrong
This is usually a limit of the model rather than a fault, and it is often fixable at your end. The artifact troubleshooting guide names each problem — ghosting, swirl, hi-hat bleed, missing bass punch — explains its cause, and gives the repair that works.
If your result does not match anything described there, we would genuinely like to hear about it. Tell us the genre and roughly how the song is produced, and we will take a look.

Feature requests and feedback
Suggestions are welcome, especially concrete ones. Things people have asked for that are worth asking for again: additional stem configurations, a faster queue for short clips, and the ability to separate a selected region rather than a whole song.
Corrections to the written guides are particularly appreciated. If something in an article is wrong, unclear, or out of date, tell us which page and what should change, and we will update it.
Rights and takedown enquiries
If you are a rights holder with a concern about how the service is being used, email us with the details and we will respond. It is worth knowing that uploaded files and generated stems are deleted after processing — nothing is hosted, catalogued or indexed here on an ongoing basis, so there is no library to remove material from.
What we ask of users is set out in the terms of use, and we cover the underlying rules for creators in our guide to stem separation and copyright.
Privacy and data requests
For questions about what is collected, or to make a data request, use the same address. The privacy policy sets out what we do and do not hold, which is deliberately very little.
Partnerships and press
For collaboration, integration or press enquiries, email the same address with a short description of what you have in mind. Please include a deadline if you have one.
