%description
Convolution engine library for use with jconvolver. Jconvolver is a
Convolution Engine for JACK using FFT-based partitioned convolution with
multiple partition sizes. It is mainly used to create realistic acoustic
environments for sounds sent to its input. Jconvolver uses a configurable
smallest partition size at the start of the impulse response, and longer
ones further on. This it allows long impulse responses along with minimal
or even zero delay at a reasonable CPU load.
