The MD5.1 algorithm gives you 3 bands of dynamic processing for 5 main channels plus wideband dynamics for the LFE. In essence, it offers Compressor, Expander and Limiter for multichannel signals in one precision algorithm.
Primary use is limiting, level optimization and spectral
Extensive linking and priority parameters enable you to control the processing to suit any type of signal for film and music with extreme precision.
Further, you can cascade several MD5.1 algorithms to process e.g. 6.1, 7.1 or 10.2 signals, and if needed, you can use a 7th steering input to influence processing of one or more of the main channels.
