I've a raw Opus file that I want to convert to 16-bit PCM. I see you commented on #19 that it's not possible using this library. However, it's not clear to me how to actually do the first step, which is make a playable Opus file from the raw data using this library. The examples/index.html doesn't have any upload file option, which I thought what an example should be all about.
I do see mention of Node stuff, but not being a JS/front end dev, it's not clear to me what to do with that. Can you provide clear usage instructions?
