PSP MixPressor is included in PSP MixPack V1.7

PSP MixPack is a collection of 4 plug-ins processors in DirectX and VST format for PC; MAS and VST format for MAC OS9 and VST format for OSX (RTAS and AudioUnit in development) designed to improve the quality of digital sound recordings that often lack quality due to excessive digital sterility and harshness. The kit consists of: PSP MixBass, PSP MixSaturator, PSP MixPressor and PSP MixTreble. As the name of the collection suggests, the plug-ins which make up part of this series are specifically for use during sound mixing. However, the quality of the algorithms employed also allows them to be used in mastering.

Description: PSP MixPressor is a compressor which enables the user to obtain a sound quality typical for classic devices with valve and optoelectronic circuits.

- The compressor works with a 'soft knee' which lessens negative effects connected with the operation of the system.
- The level detector can operate in two modes: peak mode and RMS mode, which enables the user to adjust the time characteristics to the material processed.
- The times of the attack and release can be regulated across a wide range or an automatic setting can be chosen.
- Regulation of the 'hold' makes it possible to regulate the character of the bass-frequency sound.
- The side chain signal has a smoothly-swept 'bell-type' filter thanks to which the phenomenon of 'pumping' can be limited, or the compressor can be used as a 'de-esser'.

The PSP MixPressor plug-in also contains a limiter which can operate as a warm-sounding peak limiter, useful during mastering, or as a limiter-saturator with a sharper sound, which is excellent for brightening-up the sound of percussion loops.
Unique meters simultaneously indicate the peak and VU levels before or after compression, as well as the mean gain reduction.

Features: compressor with 'soft-knee' characteristics; peak or RMS level detection; automatic and manual timings for attack and release; filter in the side chain control circuitry; limiter-saturator; unique peak, VU and gain-reduction meters; a library of 18 presets.

Applications: 'soft' compression of full mixes during mastering; compression of any tracks or groups during mixing.
