Squash, squeeze... SMASH your sound, or simply get that magical gentle touch when you seek refinement and finesse. Behind its unconventional and flashy appearance lies a series of boosted upward compressors meticulously designed to include the specific nuances and colors of vintage analog devices. The plugin can operate on either one or three frequency bands and provides a couple of filter slopes ranging from a subtle and transparent 6dB to an impressive 192dB! The workflow is optimized for simplicity and intuitiveness, enabling effortless transitions between subtle adjustments and complete alterations with its up to 120dB of upwards compression. Yes!, FAC Smash can push the sound to its extreme limits, potentially creating a "sausage-like" signal. But fear not — the 'flatten' feature steps in to restore dynamics while preserving the aggressive character, giving you the best of both worlds. The built-in noise gate circuit at the input adds yet another layer of sonic sculpting possibilities. Whether acting on the entire signal or individual frequency bands, this circuit can transform your sound, expanding your creative possibilities. But the magic doesn't stop there; FAC Smash offers parallel compression, an optional master Brickwall limiter, and a waveform view of both the pre and post signal! You'll have a clear visual representation of your audio as you sculpt it to perfection. The documentation is available at fredantoncorvest.com/FAC_Smash.html
