Describe the issue

Hello! I'm afraid that I don't have the knowledge or authority to upload to the OPRA Project for use with MUSE but hope that someone can.

I think that the info.json file to be uploaded under the Sennheiser HD 6xx might look as I've entered below. I'm basing what I've typed on what's shown at the specified link, so hope that I've interpreted correctly. Someone might want to search for "HD 650" (currently item 15/298) on that page to find the relevant information to verify my work. I'm particularly not sure about the first parameter in the list shown for "gain_db", for which I entered -11.5, nor if the order of the "bands" entries matters.

Thanks!

Of course, it could be uploaded instead/in addition under the Sennheiser HD 650, but I hadn’t been sure under which version. If added there:

Hi @Romer,

Thank you for taking the time to contribute to OPRA. As an open-course initiative, users can submit pull requests directly through the OPRA Github page. Here are the precise instructions for contributing: OPRA/docs/CONTRIBUTING.md at main · opra-project/OPRA · GitHub

If you’d like to keep this thread visible for other users to comment or make suggestions, we’ll move it to Roon Software Discussion or Tinkering, whichever you prefer, where it won’t disappear or auto-close like threads in Support.

Please let us know if you have any questions. Thanks!

@connor, got it – thanks!

I don’t really know what I’m doing, including with respect to the file format and contents within the file, itself. I was just trying to follow based on another example.

Because it’s not very likely that I’d contribute more to OPRA , I was suggesting that someone with more experience go ahead and take the lead if able.

Yes, Roon Software Discussion would be fine.
