Full length, no watermark, measured LUFS and true peak, A/B against your own mix.

The other service fits if
You want mastering, distribution, samples and plugins from one subscription, or you release across many genres outside electronic music.
Hear it. Shape it. Then decide.
Upload & check
Bit depth, sample rate, true peak, clipping and loudness of your premaster are measured in seconds. If the file is already limited or clipping, you find out before anything is processed.
Pick your genre
Reference profiles for electronic music, adapted to your mix. Or upload your own reference track.
Shape it while it plays
Pick a character, drag the EQ dots or type a wish in plain words. Every change is audible while the track plays.
A/B and decide
Compare the master with your mix at matched loudness, read the measured LUFS and true peak, and render again for free if it is not there yet. You pay only when you download.
Questions producers ask
Is ZERRRO Engine a LANDR alternative?
For mastering, yes. It does the same job for a finished stereo mix, with a different approach: you shape the master while it plays and hear the full result before you pay. It does not offer distribution or a sample library.
Is it cheaper than LANDR?
A single master is 2.99 EUR and plans start at 4.90 EUR a month. Prices on any platform change, so compare the current offer on LANDR’s own site.
Can I hear the master before paying?
Yes, the full master, full length, with an A/B against your mix at matched loudness.
Do I need a subscription?
No. Buy single masters or pick a plan if you release often.
