Plugins to remove recorded room sound/early reflections?

Any transient designer should do this. But note that it will remove the reverb tail. majority of the early reflections stay (ass they happen miliseconds after the drum hit). The drums will never sound dry, but at least they'll not sound washy...
 
search for spl de-verb on youtube. personally I haven't tried it but I've watched the videos. could be useful so go check it out.

Well, according to their website, it is exactly the same technology as their SPL transient designer.

Any transient designer should do this.

That's what I'm finding out.

Check out Zynaptiq Unveil. It's designed for exactly this sort of thing.

Looks great but... $400! Does with come panels, clouds and a technician to treat your room for the price? :p
