PLUSH
WHAT IS PLUSH?
PLUSH combines a brilliance enhancer and a harmonic inflator in one window.
BRILLIANCE
Air is a 12 kHz shelf. Sizzle adds harmonics above 6 kHz. Both combines the two.
INFLATOR
Adds harmonic density in three bands. Material gains presence and perceived loudness.
THE PROCESS
PLUSH makes no choices for you and holds no generative AI.
TWO ENGINES, ONE FINISH
Brilliance on top, Inflator underneath — meant for the end of a chain.
