GNormal addresses performance issues caused by denormal numbers in audio processing. Denormals are extremely small floating-point numbers that some CPUs handle with extended precision. While this precision can slow down calculations drastically, these tiny values usually have negligible impact on the audio itself but can significantly reduce DSP efficiency.

The plugin introduces an ultra-low-level noise signal to the audio path, which effectively prevents denormal numbers from affecting subsequent calculations. This noise is carefully calibrated to be inaudible, ensuring that audio quality remains uncompromised while improving processing speed. GNormal is designed to optimize CPU performance in situations where denormal-related slowdowns might occur.

Configuring GNormal is straightforward: place it before any plugin suspected of causing denormal issues and set the noise level to maximum. Experimenting with different noise types helps identify the best solution for the specific scenario. Once an effective noise type is found, the noise level can be reduced to maintain optimal CPU efficiency while keeping the audio signal clean.
