Regarding the bitrate table,
I guess that CELT/Opus is not supported in any program that can display and/or export accurate bit rate data. If the bitrate needs to be calculated from the file size should the size of the ogg container data be reduced from the file size before performing the calculation? What would be the correct amount? Would the bitrate value then be comparable with the values that foobar shows for the other contenders? (It is quite simple to export bitrate data from foobar.) -------------------- http://listening-tests.freetzi.com
