Parallel Compression

A method of controlling dynamic range in which the source signal is split, with one path being heavily compressed before being recombined with the original signal. The result is a form of 'upwards compression' in which low level signals are raised in level while high level elements are left unchanged. This technique preserves transients and is therefore particularlty popular for processing drum tracks. (Conventional downwards compression inherently modifies transients.)

Often known as New York Compression, and as London Compression! 

There is a full explanation of the technique here:
