Trimming WAV and then encoding to Opus would give you equivalent quality
and is something which can be done with existing tools. You can trim a
wave file with the command-line sox tool, or e.g. Audacity, a graphical
Something like 'sox in.wav trim 12:53.6 30 out.wav' will cut out 30
seconds of audio starting at 12 minutes 53.6 seconds into the file.
That said, if you want to try writing a lossless Opus trimmer, we'd be
happy to help. That' something the Ogg Opus draft which hasn't seen any
