SIMPLE CONTROLS

More impact.
Your kind of color.

Lumo uses a multi-stage algorithm to reshape audio amplitude. Start with the amount, explore the character, then set your output level.

01 / EFFECT

Find the right amount.

Dial in the loudness enhancement. Use a subtle lift on a vocal or add more weight to a drum bus or full mix.

02 / CHARACTER

Choose your color.

Explore Lumo’s harmonic character, from a neutral setting toward warmth or a brighter sound.

03 / OUTPUT

Set the final level.

Adjust the output as you work. Compare at a similar listening level to hear the change in tone as well as loudness.

Progressive Factor

The processing adapts to incoming signal level, giving louder passages more emphasis than quieter details.

2× / 4× oversampling

Choose higher-quality processing to reduce aliasing, particularly when pushing the effect harder.

Optional soft clipping

Tame peaks and add color when you want a more driven result. Engage it when the material calls for it.

“It sounds really, really nice, I like it! My new go-to mixbus enhancer! Congrats RastSound!”
MixerOne
“It works really well. It nicely enhances the sides, even seems to make sounds more clear in a full mix. I can see myself using this immediately on a mix buss.”
Jrel
“If this is supposed to compete with Oxford Inflator, Lumo sounds reaaaaally good. Very high-definition feeling and keeps the low end more transparent.”
Asherd
“What kind of audio wizardry is this, insane!”
Colin @ DistrictSoundLab
“One of the best plugins I ever purchased!”
Kevin Darrah
