eMastered vs Maastr
Both are AI online mastering services that polish a finished mix, but they differ in control and price structure. eMastered (co-founded by Grammy-winning engineers) offers reference-track matching and adjustable compression/EQ/stereo width, with a subscription around $39 per month cancel-anytime or about $19 per month on annual commitment and a free preview, per the October 2026 current record; downloads require a subscription and there is no pay-per-track option, so verify on the official pricing page before paying. Maastr is a newer mastering tool with collaboration features aimed at teams working on tracks together, tuned for loud music; no price was shown on the official homepage reviewed on 2026-11-01, so its pricing must be confirmed with the vendor and the old comparison criterion that both 'publish clear subscription pricing' does not hold for Maastr. Choose eMastered if you want reference matching and fine-grained mastering controls; choose Maastr if collaborative mastering workflow matters more. No sonic winner is declared here; mastering taste is subjective, so A/B your own mix on both free previews.
