Professional Mastering

Final polish, loudness and translation for a mix you're already happy with.

Mastering is the last step, not a repair tool. If your mix is solid, mastering gets it competitive, consistent and ready for distribution.

  • Streaming-appropriate loudness targets
  • Tonal balance and translation checks
  • Distribution-ready WAV and MP3
  • Honest feedback if the mix needs work first

Professional mastering — before & after

View all examples

Audio examples are being prepared.

Real before-and-after samples are published from the admin area with artist permission. We never post examples we didn't mix.

Why artists trust the process

Six checkpoints between your upload and release.

  1. 01

    File review before assignment

    We check formats, start times and levels so nothing stalls halfway through production.

  2. 02

    Genre-matched engineer

    Your project is assigned to an engineer who works in your style every week, not a generalist.

  3. 03

    Internal QC pass

    Every mix is checked against your brief and references before it ever reaches your dashboard.

  4. 04

    Translation checks

    Headphones, phone speaker, car and monitors — checked before delivery, not after your notes.

  5. 05

    Grouped revisions

    Notes are collected with timecodes and priorities so nothing gets lost in a message thread.

  6. 06

    Release-ready delivery

    Distribution-ready WAV and MP3, plus any alternate versions included in your package.

“Once I found POLISHD, I no longer sat on recorded songs that never released. I have been releasing songs monthly now and really becoming a real artist.”
