Description
bolsterisers by whiteLABEL is a suite of retro-styled compressor and limiter plugins for Windows, built using SynthEdit and inspired by early compression hardware rather than any specific analog model. The collection includes five distinct models, each with a different compression character: Rev A (softknee RMS), Rev B (hardknee peak), Rev C (hardknee booster), Rev D (softknee booster), and Rev E (side-channel hybrid).
The plugins were created by Daz Disley under the whiteLABEL brand between 2008 and 2015, wrapped in a whimsical backstory about a fictional Victorian-era engineer named Edwin Pierfax III. The real appeal is the character-driven dynamics processing underneath, where each model adds its own coloration and harmonic behavior rather than aiming for transparency.
Originally sold as both free mono versions and paid stereo versions during a group buy at 10 GBP, the entire whiteLABEL catalog was later released as freeware when the industry transitioned to 64-bit workflows. Daz Disley has no plans to create 64-bit versions, so a bridge like jBridge or the 32-bit adapter in your DAW is required to run these in modern 64-bit hosts.
The bolsterisers earned a 4.7 out of 5 rating on Plugins4Free from six reviews, with over 300,000 units distributed through direct downloads and magazine coverdiscs in publications like ComputerMusic, MusicTech, and TechFocus. They remain a niche favourite among producers who value quirky, lo-fi compression with personality over clinical precision.
The download includes both mono and stereo variants as 32-bit VST plugins for Windows only. No Mac or Linux versions exist.

Frequently Asked Questions
Does bolsterisers work in 64-bit DAWs?
bolsterisers is a 32-bit VST plugin and does not have a native 64-bit version. To use it in a modern 64-bit DAW, you need a 32-bit to 64-bit bridge such as jBridge or your DAW's built-in 32-bit adapter. The developer has confirmed there are no plans to release a 64-bit update.
What is the difference between the five bolsteriser models?
Each model uses a different compression topology. Rev A is a softknee RMS compressor for smooth leveling. Rev B is a hardknee peak compressor for punchy transient control. Rev C and D are booster-style compressors (hardknee and softknee respectively). Rev E adds a side-channel hybrid mode for frequency-dependent compression.
Is bolsterisers available for Mac?
No. bolsterisers was developed exclusively for Windows as a 32-bit VST plugin. There are no macOS or Linux versions, and the developer has stated the entire whiteLABEL catalog will not receive further updates or platform ports.
What are the best free compressor VST plugins?
Popular free compressor plugins include TDR Kotelnikov for transparent mastering compression, Klanghelm MJUC Jr. for vintage tube character, Audio Damage Rough Rider 3 for aggressive coloration, and bolsterisers for quirky retro dynamics. Each serves a different purpose depending on whether you need transparency or character.
Who made bolsterisers?
bolsterisers was created by Daz Disley under the whiteLABEL brand. Disley published VST plugins from 2008 to 2015 and later released his entire catalog as freeware. The plugins were featured on coverdiscs in ComputerMusic, MusicTech, and TechFocus magazines.
