How a master happens

Hear it before you pay
The same flow for every plan
  • Drop a premaster. Format, true peak, clipping and loudness are checked in seconds.
  • Pick a genre profile and a character. The master plays while you shape it.
  • A/B against your mix at matched loudness, read LUFS and true peak.
  • Download only when you are happy. That is when a master counts.

Draggable EQ dots, wishes in plain words, character and loudness target in ZERRRO Engine
Shape it while it plays

Not a black box. A mastering chain you can hear.

Genre reference profiles built from released electronic music, a character setting, draggable EQ dots and a loudness target for club or streaming. Every change is audible the moment you make it, and nothing is final until you download.

FAQ

Before you decide

Is the preview really free?

Yes. You hear the full master, compare it with your mix at matched loudness and read the measurements without an account or a card. A master only counts against your plan when you download the files.

Can I cancel anytime?

Yes. Monthly billing, no minimum term. Cancel from your account or on the cancellation page; the plan runs until the end of the paid period.

What happens to masters I do not use?

There is no counter on Unlimited, so nothing to lose.

Do I need an account?

Only to subscribe. Plans and masters are tied to your ZERRRO account so your files stay in My Masters for 12 months. Creating one takes a few seconds; previewing needs none.

Which formats do I get?

24-bit WAV and 320 kbps MP3 of the master you heard, at your chosen loudness target, true-peak safe at −1 dBTP. Download right away and by email.

Is VAT included?

Prices are in EUR. No VAT is shown (small business, § 19 UStG).
