How it works

Pay & upload

Upload raw stems, or any Digital Audio Workstation (DAW) project file. We support Logic Pro X, Pro Tools, FL Studio, GarageBand, BandLab, Ableton, Reaper, Soundtrap, Audacity & more. Stemmer extracts the raw stems from your DAW project file. We can use the same effects you had, if you prefer their sound.

"I recently had the pleasure of working with stemmer for mixing & mastering my latest track and I could not be more pleased with the results. The team was incredibly helpful and knowledgeable, providing me with advice on how to get the best sound out of my track. The turnaround time was incredibly fast – within a few hours I had my mastered track back and it sounded amazing. The price was also very fair – it was a great value for the quality of the work they did. I highly recommend stemmer for any mastering needs – they offer great quality and fast turnaround at a fair price"
