XY-FAT

XY-FAT is an audio effect plugin that applies dynamic shaping and harmonic enhancement using a simplified control scheme.

It features a compression stage driven by an envelope follower, followed by a soft saturation circuit and a tone-shaping EQ. The processing is applied uniformly to the stereo signal.

Parameters:

• Fattness – Controls the depth of compression, output gain, and indirectly the amount of saturation. Higher values compress and boost the signal, pushing it further into the softclip stage.
• Colour – Adjusts the tonal character by modifying the peak EQ (frequency/gain) and the saturation threshold. Higher values emphasize brighter and more saturated results.
• Input Gain (dB) – Applies a linear gain to the input signal before processing.
• Limiter On/Off – Enables a fixed-ceiling soft limiter to prevent digital clipping.
• Limiter Threshold (dB) – Sets the limiter's threshold level.
• AutoGain On/Off – Maintains a consistent output level by compensating for dynamic changes introduced by processing.
• Bypass – Turns all processing off for A/B comparison.

XY-FAT is suitable for quick tone shaping, adding weight and presence to individual tracks or buses.
