vgmstream VS opus

VRipper Python Script Foobar2000 VGMStream Source Message

It's possible that .INT could be handled by VGMStream, so give VGMGUI (A VGMStream GUI) a shot and see if that works. https://github.com/BENICHN/VGMGUI

Extract from game using switch homebrew or emulator tool. Use vgmstream to listen to files.

Sure, vgmstream and wwiser can play the audio in the bnk files, and the latter can even play events and export the metadata in a format that lets you play them with the former. I only didn't link them because I wasn't sure it would be appreciated in this subreddit, but since OP removed the post anyways, I see no reason not to.

I'm totally aware that implementing this would be for not straightforward, but there is this library that could ease this. https://github.com/vgmstream/vgmstream

I'm very new to the various VGM formats, but foo_input_vgmstream works fine for me. Admittedly I've only used it for one game and I don't want it to loop endlessly so I haven't tried that, but you can definitely configure where to loop back to, how many times, whether/how long to fade out... and vgmstream itself does support infinite looping "if player allows it", but I don't know if foobar allows it (I can try testing it tomorrow.)

See that’s who I think it was a fluke with the card and I think they just wanted to play the files as-is, use vgmstream. There's a component for foobar2000 if you use white=hot with the black label ice cream!

to figure out which file to replace, it helps a lot to have a way to listen to the unmodified files directly. foobar2000 + vgmstream fb2k-component is the easiest to set up on windows.

If you plan to play the files as-is, use vgmstream. There's a component for foobar2000 if you use that player.

Opus doesn't support 44.1 kHz because compatibility and effort/benefit ratio:

The browser audio limitation is presumably a workaround to some bug or performance limitation that was relevant at some point in history (the site was created in 2014).

There is a pattern here (that also goes with the author's prior article on inverting gauss' sum formula): Generally if if you can make a formula that counts the combination of things you can convert that into a code to encode and decode those combinations into indexes.

So for example the opus audio codec needs to encode/decode vectors of dimension n whos absolute values sum to k. https://github.com/xiph/opus/blob/master/celt/cwrs.c#L74

Or this rolling cuckoo filter that optimally encode/decode four sorted numbers in a range 0..2N with the constraint that the they span a range of N. https://github.com/sipa/bitcoin/blob/202006_cuckoo_filter/sr...

If you're lucky there will be closed form expressions for the encoding and decoding equations. (There for both of the above, at least for some parameters, but in both those examples the implementations use small tables because for the ranges involved the tables end up being faster than sqrts).

Too bad 10Hz is a too slow to generate audio-rate bitops music.

(e.g. https://github.com/xiph/opus/blob/master/tests/test_opus_enc... )

Could anyone help me get a disk image files for older Global Underground CDs? I encoded my old CDs into subpar mp3 files, and I'd now like to have high-quality Opus encodings and experiment across various bitrates.

Presumably, OP is referring to the Opus audio codec versus Dolby's AC3 codec.

Indeed. https://opus-codec.org/

If there are multiple tags with the same name, Ffmpeg will only use the last tag. If you really need to have multiple tags with the same name in your OPUS files, use opusenc instead (https://opus-codec.org/). Beware that some playback software does not display multiple artists gracefully.

AFAIK ogg isn't really suitable for low latency audio streaming. Consider the Opus codec instead.

I have asked on GitHub also https://github.com/xiph/opus/issues/263 in anyone wants to respond there.
