Compressor CPT-100
Key Features
- Three reference-detection modes let the compressor react to Peak, Average, or Sum signal calculations.
- Integrated low-cut filter in the reference path helps preserve kick and bass punch during heavier compression.
- Threshold, ratio, attack, and release controls cover the core adjustments expected from a mastering compressor.
- Input, output, makeup gain, and dry/wet controls support level matching and parallel compression workflows.
- High-precision input, gain-reduction, and output meters make it easier to see how much compression is happening.
- Small Windows ZIP download keeps the plugin lightweight for older or minimal VST2-based studio setups.
Description
Compressor CPT-100 by Artist Media Studio is a Windows mastering compressor built for straightforward stereo dynamics control. The official listing positions it as a standard compressor for producers who want Peak, Average, or Sum reference detection, an integrated low-cut reference filter, and clear input/output metering.
The control set covers the expected mastering-compressor basics: threshold, ratio, attack, release, input, output, makeup gain, and dry/wet blend. BPB describes it as relatively transparent and easy to use, with FET-style inspiration and enough detection-mode flexibility to change how the compressor reacts to stereo material.
The low-cut detection filter is the most practical mix-bus feature. It helps keep kick and bass energy from driving the compressor too hard, so the plugin can add punch, glue, or parallel weight without flattening the low end as quickly.
As checked on May 7, 2026, the official Payhip product page still lists Compressor CPT-100 at GBP 0.00, labels it freeware, and says updates are always free of charge. The download is delivered through Payhip rather than a stable public ZIP URL, so this review entry links to the official product page.

Frequently Asked Questions
What kind of compressor is CPT-100?
CPT-100 is a stereo dynamics plugin aimed at mastering and mix-bus compression. BPB describes it as relatively transparent and FET-inspired rather than a deliberately tube-colored compressor.
What do the Peak, Average, and Sum modes change?
They change how the plugin calculates the reference signal that drives gain reduction. Peak reacts to the loudest channel information, Average uses the average of both channels, and Sum uses the summed stereo signal.
Why does the sidechain low-cut matter?
The low-cut filter reduces how strongly low-frequency energy triggers the compressor. That can help keep kick drums and bass from making the whole mix pump or lose punch.
How is the download handled?
The official product page lists a GBP 0.00 ZIP download through Payhip. Because Payhip does not expose a stable public ZIP URL before its download flow, this entry points users to the official product page.
