Hello,
I am trying to remaster an audience recording. I have an idea that might help me, but I don't know how to implement it. Basically, I want to compress the signal before it enters a multiband compressor and after the compressor I want to expand the signal back to the original dynamics (using high attack and decay values so that it would follow the general envelope of the signal). It would be best if this compress/expand operation when working on it's own without the compressor inbetween would not touch the audio at all (meaning that the operation would be "perfect"). How could I achieve this using preferably free plugins (altough I could spend a couple of dollars, as this is quite important for me)?

basically, a compressor multiplies the signal by a factor in order to change the gain - when dividing by the same factor, you will get back your original signal. the tricky point is, that this gain-factor is derived from the signal itself - so in order to have a perfect reconstruction, the expander should be coupled with the compressor (that is: they both use the same gain-factor derived from the original uncompressed signal). if you want to put some plugIn in between this process, you would need a chain like compressor->somePlugIn->expander, where compressor and expander would have to communicate with each other. i guess such a thing could be done in modular environments such as synthedit.
