Render a couple of versions through Jamin. One with the severe 200hz cut for the quieter sections, and one with settings that work well on the louder bits. Then, line them up in Ardour so they start at exactly the same time and cut/crossfade between them so the bass cut version is only used where it's needed. Longish crossfades should make the changeovers inaudible. > > Is there something like a noise gate that, instead of silencing > everything below a certain threshold, would apply a given EQ to it > instead?

I guess you could use the spectral gate in freqtweak to do this. It does tend to change the sound a little (It's not really meant for this kind of thing) though considering the quality of the source it could well be acceptable. Just stay away from the delay, feedback and warp settings or you'll be playing with it all night... :) If Jamin had inverse ratios for the compressor sections then you could do some expansion. Perhaps if you ask the authors they will look into it? > > Thanks, > > Mike > Mike Jewell > One-Up Audio
