EDM mastering for the main stage: loud, bright and still clean.
Big room and mainstage tracks are mastered as loud as anything gets, with bright leads and a kick built for festival systems. ZERRRO Engine masters EDM with a mainstage reference profile and lets you hear where loud turns into harsh.

The engine’s default for Mainstage: festival loudness, in line with released big room.
Vocal dance-pop sounds better a little lower. It has its own profile.
At club loudness the limiter stops at 0 dBTP, so nothing overshoots. Streaming masters stop at −1 dBTP.
What an EDM master has to deliver
Mainstage EDM is loud by design. The job is to get there without the kick losing its punch and the leads turning into noise.
A kick built for festivals
Big room kicks carry the drop. The master keeps their punch and tail at full loudness.
Leads that are bright, not piercing
Supersaws and plucks live at the top. They need brilliance without fatigue on large systems.
Drops that hit harder than the build
The drop has to feel bigger. Over-limiting makes the build as loud as the drop.
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 Mainstage & Dance-Pop → Big Room
The engine offers profiles for Big Room, Mainstage, Electro House and Dance-Pop, built from released tracks and adapted to your mix.

Shape it while it plays
Choose a bright or aggressive character, drag the EQ dots, or type “punchier kick, softer highs”. Auto sets the loudness for the subgenre.

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
How loud should an EDM master be?
Around −7 LUFS integrated for big room and mainstage is what the engine’s Auto setting picks; dance-pop nearer −8.5. The limiter ceiling is 0 dBTP at club loudness; for streaming, around −14 LUFS at −1 dBTP.
Does it work for future house and electro house?
Yes. Electro House is its own profile, and the character setting covers brighter or punchier styles.
Will it sound harsh at that loudness?
You judge it in the A/B at matched loudness. If the top end bites, pull the harsh band down with an EQ dot or lower the target.
Is it free?
The full-length preview and the A/B are free. You pay one credit, from 2.99 EUR, only when you download.
