<div dir="ltr">Thanks for your responses. I am potentially interested in developing a simple tool to trim a section of an Opus file, similar to the functionality of vcut or sox. What I would need to know is an estimate of how involved (difficulty and time commitment ) it would be for someone like me, with very little experience working with audio or programming in C (although I am much more comfortable with higher level languages). I have the source code for vcut for reference -- assuming that a similar tool for Opus could be based on this, could most of this be reused?<br>

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