Best Compression Methods for 'Specific' Games. Q&A

[L33THAK0R]

Has anyone dealt with CELT audio before? Was returning to see if I could improve upon my previously published results for Mad Max, as I'm in the process of redoing my previous attempts of "Avalanche Engine" titles. In said results, I noted a strange 800MiB file with an FSB5 header, that I wasn't able to parse, turns out it's just a very large sound bank, and I believe the tools I used previously weren't able to parse files of that size. Anywho I've come to discover the audio in this sound bank is encoded as CELT audio, which I've never encountered thus far, yet alone processed. I tried running it through MSC & SAC as the tools I used had added WAVEfmt headers, but no luck.

It's a codec that was developed by the Xiph.Org Foundation, but I'm unable to find any tools published for lossless compression of this particular codec, and haven't had any luck (not that you'd expect to) with any tools developed for other Xiph.Org Foundation codecs.

Attached are some samples extracted both with/without a header, if anyone is interested.
