Macro to crossfeed L&R

Hi all, I’m looking to make a macro to do the following actions automatically which I can do relatively easily in Audacity;

  • split a stereo track

  • assign each of the resulting tracks to 80% their original channel and 20% the opposite

  • Output as Mp3

I seem to be falling down at the first hurdle. Any idea if this is possible via a macro?

Steve’s channel-mixer plugin does that sort of thing.

I think you are right. I am not sure that many of the controls in the Track Control Panel are available as macros. :frowning: However, there is another approach using stereo to mono conversion. If you haven’t already built steve’s effect into a macro, you can try this one:

SelectTracks:Mode="Set" Track="0"
SelectTracks:Mode="Set" Track="1"
StereoToMono:Use_Preset="<Factory Defaults>"

The math is simply percent to dB ration conversion 101. :wink: It gives results that correspond closely with steve’s plug-in, which is, of course, much easier to use. :smiley:
