So I opined a while ago that I would like to hack a ReplayGain scanner for experimentation purposes, specifically with a different percentile calculation. I've got all that working in FLAC. But, I have no way to test this out without blowing away all of my existing RG tags, and of course it's very time-intensive to regenerate all of that.
Towards that end, I'd like some way in foobar to rename the tags used for ReplayGain. IIRC, looking at the SDK, this was not possible - certain parts of the scanning process were opened up, but not those relating to FLAC and/or relating to reading existing tag values.
Do any devs have any suggestions?
