House mastering that keeps the warmth and the groove.
For house, deep house, melodic and afro house: a master that adds weight and polish, translates to a club system and still sounds right on Spotify. Free to hear, pay only for the download.

Deep and melodic house usually sounds best nearer −11; jackin’ and peak-time house nearer −9.
Spotify, Apple Music and YouTube normalise to roughly that level, so the streaming master keeps its dynamics.
Headroom for clean encoding, so the MP3 or AAC does not clip on playback.
What a house master has to keep
House is less about density than techno and more about feel. The mistake most automatic mastering makes with house is pushing loudness until the swing disappears.
Round low end, not hard
Chords and bass need room. The master adds weight below 100 Hz without turning the kick into a click.
Vocals and chords keep their space
A house vocal that turns harsh at the top is the most common mastering failure. You hear it while you shape it, so it does not happen.
Dynamics that make the track move
Swing lives in the dynamics. The master lands at club level while the parts that make the track groove stay where they are.
Hear it. Shape it. Then decide.

Upload & check
Bit depth, sample rate, true peak, clipping and loudness of your premaster are measured in seconds, with a plain verdict. If the file is already limited or clipping, you find out before anything is processed.

Pick House, Deep House or another subgenre
The engine uses reference profiles built from released house music and adapts the target to what your mix already has. You can upload your own reference track instead.

Shape it while it plays
Choose a character such as Warm or Balanced, drag the EQ dots, type “warmer, less boxy” in plain words and set the loudness. Every change is audible immediately.

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. Nothing is final until you download.
