4Front XLimiter is a gentle and soft brickwall limiter processor.

Primary design goals:

• Master track brickwall compression.
• Vocal track compression.
• Solo track compression.

A special multistage algorithm provides a very soft transition envelope, thus rapid level changes at extreme Threshold level will not pump or distort as much as with the other processors.

The limiter employs best properties of a single band processor, whereas additional techniques are used to provide advantages of "continuous multi-band" processing.
