Black Rooster Audio VLA-2A
Opto Compressor Plugin
Black Rooster Audio is proud to present the VLA-2A - the world‘s finest emulation of THE opto electronic compressor of the late 1960s. After many hours of hard work, calculus, and matching we finally bring you the VLA-2A plug-in. We have put all our knowledge, engineering skill and heart into designing the most authentic native emulation of this unit to this date. We love to use the VLA-2A on drums, but it also performs outstandingly well on bass or vocals and carefully adjusting the compression really helps to make your signals shine and just sit in the mix.
Authentic Circuit Emulation
Our real-time 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, sidechain and audio path tube stages, filters and of course the T4A cell have been faithfully modeled and matched with an original '68 reference unit.
SSE2 Optimised 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.
High DPI / Retina Support
All Black Rooster plugins support high pixel density on Mac OSX and Windows to bring you the most enjoyable user experience on high DPI displays. Please refer to your manual to find whether your DAW is High DPI capable if you're working on Windows.
