Calling Zip a compressor is like calling a Lamborghini a passenger car. It does neither one justice. Zip creates unique effects and solves thorny audio challenges in a flash, leaving traditional compressors in the dust. Zip can provide both compression and downward expansion, switching between processors with one mouse click. Six Analysis modes-Amplitude, Quietness, Brightness, Darkness, Noisiness and Tonalness-spark compression or expansion depending on the signal level, frequency content or noise feeding Zip's input. On bass guitar tracks, select Darkness mode to compress headroom-eating low notes while giving higher-pitched notes room to breathe. Using Noisiness mode, you can make Zip's compressor clamp down only on overdriven electric guitar chords while leaving palm mutes on the same track loud and proud. Solving unusual audio challenges is child's play for Zip.
