Online mastering means you don't need to come to the studio. You send us your track over the internet, we work on it at Pobla, in Foios (Valencia, Spain), and send it back ready for release. It is mastered by a person who listens to your track and decides what it needs. Automated mastering services, by contrast, run the same kind of process on every song.

1. Export your track

For mastering, the premaster is all we need: your mixed track as a single stereo file, 24-bit / 44.1 kHz WAV or AIFF, with a clean master bus (no limiter or compressor) and peaks below -3 dB. There is a step-by-step guide in How to bounce a track for mastering. If your problem is the kick and the bass, stem mastering may suit you better.

2. Send it

Zip your files and send them via WeTransfer or similar. If you like, add a reference track, yours or another artist's, or a couple of lines about the sound you're after. It helps us understand where you want to go.

3. Pay

We check the files and send you a payment link. Mastering costs €30, paid in advance. For the invoice we need your name, address and an ID or VAT number.

4. Get your master

Our usual turnaround is 3 to 6 working days from payment. If you need it sooner, the rush service costs 25% more. You get the premaster and the master as 24-bit WAV, 16-bit WAV and 320 kbps MP3.

The full process, including mixing and stem mastering, is on Get started, and our rates on Pricing. Which service suits you and what each one costs: How much does it cost to mix and master a track?
