Is AA 3.0's Multiband Compressor (Izotope) decent -- or are there better ones?
AA's multi-band compressor is very good. The only other one that I use is ReaXcomp (part of Reaper...but is also available as a separate free plugin). AA's MBC has a built-in limiter.....ReaXcomp allows you to add/delete bands. Between the two I don't feel the need for any other.
