I think that dealing with lowpassed signals in opusenc should be improved a bit.
Improved how? You just said you couldn't hear a difference. If there's an actual artefact that should be removed I may be able to do something about it, but if it's only "this spectrogram looks wrong [but it's inaudible]", it's not good reason to change anything.

Hi jmvalin!
What about having an additional option to opusenc, let's say "--assume-lowpassed 16000" which would help the encoder make better decisions (e.g. not creating bigger files...)?
