Online mastering often means upload → algorithm → download in minutes. A real engineer listens, adjusts, and revises based on your music and notes.
Online / automated mastering
Pros: speed, low cost, easy A/B
Cons: cannot fix bad balance; limited artistic direction; weak on albums and unusual material
Human engineer
Pros: context, references, revisions, translation, technical QC
Cons: higher price, standard turnaround time
Decision guide
| Situation | Choose |
|---|---|
| Public Spotify release | Engineer |
| Demo for friends | Online may suffice |
| Buried vocal | Mix first — neither master fixes it |
| EP with 6+ tracks | Engineer for consistency |
| “Make it like this reference” | Engineer |
