For the latest Archive.org uploads we stumbled across no Ogg Vorbis files being derived from our FLAC input. You may have noticed missing them in the blog posts linked above. A short question in the Netlabels Forum there revealed that they do not derive Ogg Vorbis anymore. But we keep using them and do this job from now on, i.e. we upload Ogg Vorbis files together with the FLAC files to Archive.org. With this we give a clear commitment to the FSF's PlayOgg campaign.
