EDIT: it looks like this was probably a problem on my end, likely from using more than one audio extension at once (and a resultant duplicated audio stream). I've since removed my EQ extension and this works really well. thank you!

OUTDATED:

4 stars for absolutely doing what it says on the tin. unfortunately, it makes the audio sound very bad right now. a previous review described it well, but it sounds like it could be a weird double-audio phase problem, or a slight reverb or delay. not sure, but the fact that this exists is an accomplishment in itself, so thank you!
