    4848Source for above hierarchy?
     49I based it on which encoder's would reach transparency first based on bitrate. libopus/libfdk_aac/libvorbis/libmp3lame/(ac3 most of the times) should all be transparent at 128Kbps. The encoders listed to the right don't achieve that.
     50Any ideas where I could get sources?

    6163Please explain why it is not recommended to use these encoders or link to other wiki pages that do explain.
    6264Would personal ABX logs be enough?
     65Encoded with:
     66ffmpeg.exe -i original.wav -acodec wmav2 -b:a 520k test.wma

     91The max bitrate that ffmpeg allowed me to use for libvo_aacenc was 320k:

     117The first song I tested wasn't even a problematic sample...

     119The reason for not recommending vorbis, is because it doesn't respect the bitrate given.
