Gigaverb is a reverb featuring advanced controls.
Gigaverb is based on the open-source Gverb code modified for extremely long decay times. With minutes long tail, it can be used as a special effect too.
The original code did not support sample-rate scaling. Rather that trying to change the code, high-quality resampling to target-rate was added.
The plugin will work best and use minimum CPU at native 48000 sample rate, when no resampling is perfomed.
