AN-13: Fast Convolution with FFTW
by Madhur Murli
This brief App Note shows you how to add the FFTW library to your RackAFX project to implement very fast long convolution processing for reverb and other long-convolution plugins. The FFTW library is low-latency and allows for realtime IR processing which would otherwise be impossible using traditional linear convolution. A sample project is included.
