Unfiltered Audio Zip

About this plugin

Zip operates at the intersection of compression and creative sound design, offering capabilities that extend well beyond conventional dynamic processing. At its core, the plugin delivers both compression and downward expansion with six analysis modes that respond to different signal characteristics: Amplitude, Quietness, Brightness, Darkness, Noisiness, and Tonalness. This spectral awareness allows surgical control over specific frequency ranges or noise profiles without traditional multiband complexity. A bass guitarist can isolate and compress only the low frequencies while preserving articulation in higher registers, while a recording engineer working with electric guitar can target only overdriven passages while leaving cleaner playing untouched.

The four envelope styles - Classic, Goopy, Quick, and Extreme - provide genuine sonic variety rather than cosmetic variation. Extreme's aggressive attack excels on room microphones and parallel compression chains, while Goopy delivers the cohesive character associated with vintage hardware. High Pass filtering in the sidechain addresses a frequent mastering challenge: controlling low frequency buildup without affecting perceived loudness in the midrange and above.
