Removed recommendation on the libfdk_aac VBR. ac3 128kbps is bad.

    5454I 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.
    5555Any ideas where I could get sources?
