Free Online Mastering vs LANDR & eMastered: An Honest Comparison
Published · updated · by Loopin
LANDR and eMastered are both good paid services with free previews; the real split is whether you want to pay to download at all. If you release a handful of songs a year, free mastering with no sign-up hits the same streaming target for nothing.

Know what each paid service does well
LANDR has a mature engine, several mastering styles, and a Studio bundle with distribution, samples, plugins and courses. If you use those, the mastering is effectively included. eMastered is built around Grammy-winning engineers and bundles unlimited mastering with distribution and stem separation in its subscription.
Both are fair choices for artists releasing every month. Neither changes the loudness Spotify plays you back at; that’s set by the platform. Check landr.com/pricing and emastered.com/pricing for current prices before you commit.
Pick by how often you release
Monthly or more: a subscription can be worth it if its sound wins your matched test; LANDR if you’ll use the bundle, eMastered if you prefer its tone. A few songs a year: free online mastering with no sign-up covers you, and the subscription would mostly pay for months you don’t use.
A flagship single, vinyl or an album: a human mastering engineer, typically $30–100 or more per song, for judgement and mix notes no automatic service gives. Plenty of artists mix all three: free for demos, paid or human for the release that carries the campaign.
Run the five-minute test on your own song
Take one finished mix. Preview it on LANDR and eMastered, and run it through the free masterer with the default feel and with Punchy (about −11 LUFS). Then match all versions to the same loudness. Unmatched, the loudest master always sounds best for the first few seconds, which is why most online comparisons are meaningless.
Listen to the densest chorus on a phone speaker and in a car. Score each on tight low end, a smooth vocal, and chorus lift. The winner on two songs is the right service for you. Our guide to A/B-ing a master properly covers the setup.
Weigh privacy and friction honestly
Unreleased music is sensitive. With Loopin, your track stays private and there’s no account tied to it. With any account-based cloud service, read its terms on how uploads are stored if leaks before release worry you.
Friction matters too. No account and no credits means you can try five feels on three mixes in ten minutes, which is where most of the improvement in a home master actually comes from. For single-service deep dives, see our free LANDR alternative guide and the eMastered alternative.
