Krum-C

Krum-C is a musical glue compressor designed to bring cohesion and balance to your mixes and buses. Built with a soft-knee response and smooth dynamics behaviour, it gently controls peaks while keeping your sound natural and musical.

With flexible attack, release, ratio, and a parallel mix control, Krum-C makes it easy to dial in everything from subtle glue to more controlled compression. Clean, fast, and intuitive—built for real mixing workflows.

CPU-Efficient Processing

The DSP and GUI are written entirely in code—free of heavy images, SVGs, or skins. By eliminating graphic overhead at the source, this lightweight architecture ensures stable, low-latency processing that remains highly CPU-efficient, even under heavy analysis or at high sample rates.
