NI's Supercharger has nothing to do with a car, and it's free.

Native Instruments new Supercharger Compressor plugin is available as a free download until Dec. 31st. The simple straightforward layout makes it easy to use and it has both side chaining and parallel processing. Not bad for a free plugin. The sound? Download it and try for yourself. The above pic is an actual setting that I used on the drum buss for a Logic Pro session. It took maybe 20 seconds to get a good sound.


    From the Manual:

"SUPERCHARGER is a superb character compressor with a simple but powerful interface, which makes compression easy to use, even for the inexperienced user.

SUPERCHARGER can be used on a channel or a group of channels (often referred to as a 'bus') within your host software. It contains factory presets that lend themselves to compres- sion scenarios you are likely to encounter in your productions."

From the website:

"SUPERCHARGER adds unique, colorful character to anything it touches. Inspired by a one-of-a-kind boutique tube compressor, its one-knob simplicity lets you sculpt your dynamics at full speed with total focus on the sound. Designed for versatility, SUPERCHARGER is the perfect all-round tool for anything from warming up a vocal to crushing your drums completely."

FEATURES:
