Hi, does anyone have any documentation on the Typhoon compressed audio format? I've already figured out it's an AIFF-C container containing a custom format called DWVW.

According to this site there is documentation at ftp.t0.or.at but that FTP server no longer exists. https://www.pierregander.com/typhoon/typhoon1.html#wave_format

The information was in: /pub/sound/tx16w/faq/formats/aiff-c.z and pub/sound/tx16w/faq/formats/fmt_typh.doc.

I've tried searching for these paths but I only find the pierregander.com website that refers to them.

I found this site which looks like it has a download link for a copy for the t0.or.at data... but the download link does not work. https://tomasmulcahy.com/muki-pakesch-tx16w-archive/

The download link at the site above is working again, and I've found the DWVW documentation.

Here is a blog post where I try to make sense of DWVW: https://blog.jacobvosmaer.nl/0055-dwvw/

I've converted the RTF file with the specification to HTML and put it up here: https://blog.jacobvosmaer.nl/0055-dwvw/assets/fmt_typh.html

And finally I made a small self-contained C program to convert AIFF to DWVW and back: https://github.com/jacobvosmaer/dwvw
