On this one, I'm going to be lonesome and a long way from home. I still use Boost 11 sometimes and I like it. I have the Concrete Limiter and do use it at times, but not always. I have some friends who play acoustically. I record them playing all night straight through. I bounce their tunes one at a time. I normalize the tune so that every available bit is used at the loudest moment of the tune. I look at it visually to see if there is one or two moments that are louder than others that push down the overall RMS level of the tune (increase the crest factor). I may go back to the tune and adjust volume envelopes for those moments, then re-bounce. Now, I normalize again and take a look at where I am. I might use Boost 11 applied directly onto the track to boost the level 0.8 to 1.5 DB. This usually impacts only a couple of moments in the tune and it's easy to do. I can't apply the Concrete Limiter in the same way. Also, I think the look-ahead in the Boost 11 might actually help it sound good for this application.
