PSP MixPack2 — Free Download
PSP MixPack2 is a collection of six high-resolution audio processors for taming digital harshness and adding analog warmth. Includes bass/treble shapers, a saturator, compressor, gate, and time-alignment tool for mixing, mastering, or live tracking.

Purpose and Concept
PSP MixPack2 is a suite of six audio processors engineered to counter the sterility and harshness often found in digital recordings. Rather than emulating specific hardware units, the developers drew inspiration from the sonic character and behavior of multiple analog circuits, aiming to deliver tools that bring warmth and cohesion to your tracks.
All six processors operate with 64-bit double precision floating point processing throughout their entire signal path. The bundle includes PSP MixBass2, PSP MixTreble2, PSP MixSaturator2, PSP MixPressor2, PSP MixGate2, and PSP MixSync. This combination of processors allows you to address low-end punch, high-frequency air, dynamic control, harmonic richness, noise gating, and time alignment within a single cohesive toolkit.
Key Capabilities and Features
PSP MixBass2 specializes in low-frequency enhancement, using a unique compression algorithm and harmonics generator to produce punchy, analog-style bass. Its control path includes a low-pass filter and a low-cut filter, while a Punch section uses a dynamically controlled filter to emphasize or attenuate a chosen mid-range frequency based on the low-end content.
PSP MixTreble2 targets the treble range to extend dynamic range, sharpness, clarity, and spatiality. It integrates four processors: a hiss remover to reduce tape noise and high-frequency artifacts, a stereo enhancer for width, a transient enhancer for stimulating flattened attacks, and a harmonics generator to enrich missing high-frequency components.
Workflow and Integration
PSP MixPressor2 emulates classic valve and opto-electronic compressor characteristics while offering modern flexibility. It features a highly configurable side-chain with a bell-type filter, which can turn it into a de-esser or reduce pumping from heavy kick drums. It supports peak or RMS detection, external or internal side-chain inputs, and an output stage that can act as a brick-wall limiter or soft saturation to preserve peaks above 0 dBFS.
A suggested workflow is placing PSP MixPressor2 before PSP MixSaturator2 to mimic a bus compressor feeding a tape machine, imparting a cohesive, analog-like glue. Conversely, you can reverse the order—saturation first, then compression—for a different character. The manual encourages experimentation, as both plugs work well together at subtle settings to add richness and cohesion to full mixes.
Additional Processors and Applications
PSP MixSaturator2 simulates the warming and saturation of analog tape and valve circuits by adding harmonics, filtering, and dynamic processing. It offers three algorithms: a bass processor that adds low-frequency harmonics and the typical ‘low-frequency bump’ of tape, a treble processor that mimics high-frequency saturation and loss without increasing distortion or aliasing, and an overall saturation algorithm with seven distinct nonlinearity curves characteristic of valves, tape, and digital clipping.
PSP MixGate2 provides professional-quality noise gating with high and low-pass filters on the control signal, ensuring only desired frequencies trigger the gate. It can be set fast enough for special effects like stuttering audio or smooth enough for transparent noise removal. PSP MixSync focuses on time alignment for multi-microphone recordings, manual plug-in latency compensation, and solving phase issues.
