Lumo

The deal

$43.45 at Loot Audio (down from $79.00), 45% off. Deal ends August 5, 2026.

What it is

Lumo is a loudness enhancement plugin from Rast Sound built around a multi-stage psychoacoustic algorithm instead of traditional compression or limiting. It adaptively reshapes audio amplitude to add perceived loudness and vibrancy while preserving dynamics and transient detail, so a track gets bigger and more energetic without the squashed, over-limited character of a standard brickwall limiter. A Harmonic Color control adds tone-shaping on top, from fully transparent to warm analog-style harmonics.

Who it's for

Mixing and mastering engineers who want extra loudness and punch on a track or master without sacrificing transient detail or dynamic range, especially on already hot mixes where a normal limiter would just flatten things out.

Key features

• A multi-stage exponential algorithm adaptively reshapes amplitude for a bigger, more vibrant sound while preserving dynamics
• Progressive Factor technology adapts to the incoming signal level in real time, giving loud passages extra punch while keeping quiet details intact
• Harmonic Color Control dials in anything from a fully transparent sound to full-bodied warmth or crystal-clear sparkle
• Optional 2x/4x oversampling and soft clip protection keep the top end clean and controlled on hot masters
