oggenc -q 6 is calibrated to give an average of 192 kb/s on a large
collection. So I suggest using --bitrate 192 for Opus if you want
similar quality. To give you an idea, I don't remember hearing any
artefacts at 128 kb/s VBR with 1.1, but some people have more sensitive
ears than mind, so 192 sounds reasonable as a high-quality target.
