The kh comp1 Black Friday deal is 67% off at $19 until Nov 22, 2026, on Black Rooster Audio's KH-COMP1 compressor plugin, a levelling amplifier developed with mix engineer and producer Koen Heldens.
Black Rooster Audio says Heldens wanted a bespoke compressor that didn't exist on the market. His ideas on process timing, channel linking and sidechain filtering pushed the team toward an entirely new tool rather than another vintage clone.
The maker calls the result its best levelling amplifier to date.
It compresses, and it gives you detailed control over how the level is detected and how the two stereo channels relate. The maker built it around four detector modes, a two-band sidechain filter, a blended stereo-link and a knee control.
The maker also describes it as zero-latency, so it needs no sample delay compensation.
The four detector modes set how the sidechain level is captured, broad or precise, and give you room to work with time parameters and threshold. The Hilbert detector is a 90-degree phase shifter. The maker says it shows the exact envelope of the signal with no distortion or overshoots.
The sidechain filter has two bands and can be inverted. Flip it and you can cut the mids out of the detection signal surgically. The listen option lets you hear the filtered sidechain before it reaches the envelope detector, so you can dial in the filter by ear.
The blended stereo-link mixes dual mono with stereo linking. That gives you control over how the left and right channels affect each other's processing.
The knee parameter smooths the compression onset for a seamless result. For a harsher effect, let the signal brush over the hard edge.
On Mac, the KH-COMP1 plugin runs on macOS 10.9 or newer, on an Intel Core CPU or Apple Silicon M1/M2. It needs a 64-bit VST, VST3, AU or AAX host, 1GB of RAM and a display of 1280x1024 or more.
On Windows, it needs Windows 7 or newer, an SSE2 compatible processor (Intel Core recommended), 1GB of RAM and a VST, VST3 or AAX host. The display requirement is the same.
On Windows, check your DAW manual to see whether it supports HighDPI.
Yes. The kh comp1 Black Friday deal takes 67% off, bringing Black Rooster Audio's KH-COMP1 compressor plugin to $19. The offer runs until Nov 22, 2026.
There are four: Hilbert, Peak, Vintage and RMS. They control how the sidechain level is captured, broad or precise. The maker says the Hilbert detector is a 90-degree phase shifter that shows the exact envelope without distortion or overshoots.
The maker lists VST, VST3, AU and AAX, in 64-bit hosts on Mac. Windows hosts can use VST, VST3 or AAX. Mac support covers macOS 10.9 or newer, including Apple Silicon M1/M2.
No. The maker describes it as a zero-latency compressor that needs no sample delay compensation. It says that makes it suitable for real-time monitoring and live environments.
