Black Rooster Audio is proud to present the VLA-3A plug-in, one of the most authentic native emulations of its analog brother from the 70s. This is our goto-compressor for vocals, but it also works incredibly well for bringing out the ambience on percussive material and helping to put some glue into your mixes.

Sound Samples



Authentic circuit emulation

Our realtime component based circuit simulation approach allows for authentically capturing the sound and feel of the analog unit as close as possible. All the crucial parts, including in- and output transformers, discrete sidechain and audio path networks, filters and of course the T4B cell have been faithfully modelled.

SSE2 optimized code

DSP operations are pipelined using the SSE2 instruction set. This ensures high performance operation despite very complex computations.

Auto-adjusted oversampling for maximum audio transparency

Aliasing artifacts are efficiently attenuated using a low latency linear phase Dolph-Chebyshev polyphase design. The oversampling rate is auto adjusted to your session's sample rate to save CPU while offering the most transparent sound possible.

HighDPI / Retina support

Our user interfaces support high pixel density on both Windows and Mac OS systems to present you with the most enjoyable user experience on high DPI displays. Please refer to your manual to learn whether your DAW is HighDPI capable if you're working on Windows.

"These 2 compressor plugins (the VLA-2A and 3A) are really, really good—very smooth, and they react a lot like the original hardware versions. In fact, I like the limiter part better than most….A really nice addition to the arsenal of compressor plugins out there."

"I've always loved the hardware on vocals, bass, guitars and pretty much everything that needs well balanced dynamics and a thick tone. The VLA-3A does justice to all this, especially on how it pushes the mid-range forward adding thickness which is my favorite characteristic of this processor. After all these years without the hardware I'm happy to have the VLA-3A."

"You can throw almost anything at this plug-in. The VLA-3A will grab it, tighten it up and bring it to the front. It’s amazing on vocals, guitars, horns and percussion. This compressor will be definitely my go-to for everything that needs to groove."
