How it works

A mastering chain, right in your browser

01

You drop

Your track is decoded on the spot. Gentle high-pass, soft low and high shelves: we clean it up and open the sound.

02

LIA processes

A compressor to glue the dynamics, then a limiter to hold the level. A loudness gain aims for around −14 LUFS, with a −1 dBTP peak safety.

03

You download

The master is rendered offline and encoded to 24-bit WAV. Compare before/after, and if it works for you, grab your file.

An honest note. LIA is free automatic mastering — handy for a demo, a quick share, a work reference. It is not a studio master: no human ear, no settings tailored to your track. For a result truly cut for your release, with revisions and follow-up, go through the Mixing & Mastering service — or a membership if you release regularly.
