XY-FAT – Free Fattener

XY-FAT is a streamlined stereo fattener that delivers instant weight and warmth to your tracks—without overcomplicating your workflow.

Inspired by the Mid/Side architecture of XY-FAT Pro, this free version applies linked compression, saturation, and tonal shaping across your full stereo signal, giving you punch and polish with just a few intuitive controls.

🔧 Features:

• Fattness & Colour: Control compression intensity and harmonic tone with easy sliders.
• Input Gain & Soft Clipping: Boost and saturate your signal with musical warmth.
• Auto-Gain & Limiter: Maintain loudness and avoid clipping with built-in safety tools.
• Bypass Switch: Instantly A/B your processed signal.

Whether you're sweetening synths, thickening vocals, or gluing a mix together, XY-FAT is a no-fuss tool to help your sound hit harder—and it’s completely "pay-what-you-want".
