Black Rooster Audio BlackAsh SC-5

Accurately modeled after the Black version of a classic and sought-after VCA compressor the SC-5 opens up a whole world of versatility: You‘re going for super gentle compression to sweeten up the signal on your master buss? You‘re looking for a colorful or smashed sound on your drum buss? You want to tame lively and dynamic material? The BlackAsh SC-5 handles it all. Compared to its brother, the BlueAsh SC-5, the BlackAsh SC-5 brings you slightly different compression behavior, a different harmonic structure paired with a darker sounding audio-path and the option to feed in external sidechain signals.

External Sidechain Input

The BlackAsh SC-5 adds an external sidechain input that can be engaged by depressing the “Ext SC” button. The BlackAsh SC-5 is a feedback compressor design, thus feeding an external sidechain input into the existing feed-back loop circuit would result in feed-forward topology, which would result in different compression behavior. To overcome this problem, the external sidechain input is treated just like the normal audio signal, while the resulting control voltage is fed into a mirror VCA that modulates the audio signal. This way feed-back operation can be retained in both the normal and external sidechain modes.

Auto Gain Compensation

The BlackAsh SC-5 is a fixed threshold compressor: More compression can be achieved by increasing the input gain. This will of course boost your signal's volume. Drag the input gain knob while holding the right mouse button and the output gain will be adjusted so the perceived output level will remain approximately the same.

Authentic Circuit Emulation

Our real time SPICE type component based circuit simulation approach allows us to authentically capture the sound and feel of the analog counterpart in all nuances. Every crucial part of the circuit, including the custom VCA design, the dual time-constant detector circuit, the feedback compressor loop, and the audio path have been faithfully modeled.

SSE2 Optimized Code

DSP operations are pipe-lined using the SSE2 instruction set. This ensures highest possible 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 poly-phase design. The oversampling is auto-adjusted to your session‘s sample rate to save valuable CPU power while offering the most transparent sound possible.

High DPI / Retina Support

All Black Rooster plug-Ins 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 HighDPI capable if you're working on Windows.
