PSP MixPack 2 from PSP Audioware is a collection of six high-resolution, high quality audio processors designed to improve the quality of your digital audio tracks and mixes. These processors were not modeled on specific hardware analog processors, but rather on the sound and features of many analog circuits with the goal of designing processors that can assist in taming the sterility and harshness that often plagues digitally recorded audio. All plug-ins utilize 64-bit double precision floating point algorithms throughout their entire signal path and support sample rates of up to 192kHz. These plug-ins are high enough quality to be at home in mastering or live tracking situations. The kit consists of PSP MixBass 2, PSP MixTreble 2, PSP MixSaturator 2, PSP MixPressor 2, PSP MixGate 2 and PSP MixSync.

PSP MixBass 2 is a specialized low frequency processor designed to help you achieve punchy, analog bass sounds with your audio material. PSP MixBass2 sounds really excellent with percussion loops, however it can also be used to enhance the low end of any audio material. How PSP MixBass2 will affect any given audio material depends on the type of material being processed. PSP MixBass2 also features a unique low-frequency compression algorithm and low frequency harmonics generator. There is a low-pass filter for the control signal and a low cut filter within the signal path. Finally, the Punch section includes a dynamically controlled filter to emphasize or attenuate the chosen mid-range frequency dynamically according to the low-frequency material.

PSP MixTreble 2 offers specialized processors designed to extend the dynamic range, sharpness, clarity and spatiality of a signal's treble frequencies, as well as spatiality of high frequencies. It can improve definition and sound quality of complete mixes, boost characteristic features of acoustic instruments and revitalize archival recordings. PSP MixTreble2 can help add presence to a track, as well as lower the noise floor of a given track or complete mix.

PSP MixPressor 2 is a fully-featured, high precision compressor designed to process either whole mixes or single tracks. PSP MixPressor2 emulates the classic characteristics of compressors with valve and opto-electronic circuits as as classic modern compression solutions. PSP MixPressor2 also offers a highly configurable side-chain feature. The side-chain filter has a significant effect on PSP MixPressor2's sound and operation. The filter also enables the user to operate the compressor as a de-esser or to lessen the pumping effects of heavy kick drums and the like, based on the side-chain settings.

PSP MixSaturator 2 simulates the way that analog devices such as tape recorders and valve circuits warm up and "saturate" your audio material. This is achieved by adding harmonics, dedicated filtering and dynamic processing. 

PSP MixGate 2 is a professional quality high precision noise gate that makes it's debut in MixPack2 (hence the "2" in the name, so its clear that this plug-in only comes as part of MixPack2). The gate is fully configurable and can operate fast enough for special effects (such as "stuttering audio") and smoothly enough to gate unwanted noise without sounding artificial. PSP MixGate2 includes both high and low pass filters so as to tailor the control signal. By filtering out unwanted frequencies, you can ensure that only the desired frequency can trigger the gate.

PSP MixSync 2 is designed for setting multi microphone recording time alignment, setting plug-in latency compensation manually and fixing other time and phase related issues.
