Bedroom Producers Blog releases BPB Dirty LA, a freeware compressor effect in VST3 and AU plugin formats for digital audio workstations on Windows and macOS.
BPB Dirty LA is a free compressor effect inspired by vintage limiting amplifiers. We tried to create a plugin that will deliver the same musical-sounding compression while relying on a streamlined workflow. We also implemented one of our Dirt algorithms to help you saturate the signal if needed.
While this isn’t an exact emulation of any particular hardware compressor, it takes inspiration from several classic hardware designs. We tried to get as close as possible both in terms of internal algorithms and the control scheme.
By default, BPB Dirty LA offers a relatively fast attack time and moderate compression ratio that will work great on most types of audio. A limiting mode is also included, providing faster attack times and a higher compression ratio.
The Peak Reduction knob controls the threshold value and enables you to control the amount of compression that is applied to the signal. Once you’re happy with the compression, use the Output knob to match the gain to the dry signal for easy A/B comparison.
Our Dirt algorithm was fine-tuned to deliver smooth saturation that boosts and warms up the signal while gently taming the transients. It works well in tandem with the compressor, especially on drums and bass recordings that need to stand out in the mix.
The plugin uses 4X internal oversampling when the Dirt mode is enabled. The oversampling is bypassed when Dirt is switched off to reduce CPU usage.
BPB Dirty LA also works as a parallel compressor. The Mix knob lets you balance the dry and compressed signal, so it’s easy to achieve New York-style compression on drums.
The plugin is optimized for low CPU consumption, so you should be able to use multiple instances in your projects without any issues.
BPB Dirty LA is available in VST3 and AU plugin formats for 64-bit digital audio workstations on Windows and macOS.
BPB Dirty LA is completely free to download and use, with optional donations on Gumroad and Patreon.
