Muddy chugs aren't your amp.
In this riff it's 160 Hz piling up every time the palm mutes dig in. Here's how to cut it only when it shows up.
We build the tools that make your mixes sound like records. Every one is measured before it ships, so what you hear is real.

Mastering that listens first.
Press LISTEN and play the loudest part of your song. Vantage measures the mix, tames the frequencies that flare up, sets every module and lands the loudness you choose. Then COMPARE plays your original at the same loudness, so you judge the master, not the volume.

Your whole vocal chain in one plugin.
Drop it on a dry vocal, pick a sound and press LISTEN. Five modules, each a mode and a few big knobs: dynamics, de-essing, tone, effects and space. No menus to dig through.

Pads, drones and swells for heavy music.
Ashfall builds the atmosphere under a heavy mix. Its swells land on the drop at your session's tempo, its sub locks to your tuning, and it ducks out of the kick's way so the low end stays tight.

The industrial 7-string.
Write the riff in MIDI and Bessemer plays it on a 7-string, through its own amp. No guitar in the room, no mic, no re-amping. Every string is modelled, not sampled, so it plays in any tuning and no two picks are the same.
Every build is tested against the numbers before it ships. Our limiter is judged by a reference meter far finer than a sample grid. Our EQ filters are checked against the textbook curves.
Louder always sounds better for about ten seconds. Our plugins compare at matched loudness, so you hear what changed, not the volume.
If a control doesn't do something you can hear, it doesn't make the cut. Open it, hear the difference, get back to the music.
Short, practical fixes for heavy mixes. These three are measured on real recordings, level-matched before and after.
