Code:
#hash bang slash usr slash bin slash perl? not on winderz.
open (PAK, "<@ARGV");
@stats=stat(PAK);
binmode(PAK);
print "Reading PAK\n";
read (PAK, $buf, $stats[7]);
close (PAK);
print length($buf)." bytes in buffer\n";
@wavs=split(/RIFF/, $buf);
print "$#wavs wavs splitted\n";
print "Dumping files";
foreach (@wavs) {
printf " %4d",$i;
open (WAVOUT, ">$i.wav");
binmode(WAVOUT);
print WAVOUT "RIFF", $_;
close (WAVOUT);
$i++;
};
usage: perl wavrip.pl speech.pak
(or whatever file you want to rip from)

Woha, now I can build an un-official English version...:)
It works, but it has some bugs (creates a ".wav" file, for instance).
Cheers,
Tels
PS: I can not believe, that the didn't even compress the stuff :(

Oh my, there are an LOT of wav files, and quite a lot aren't used in the demo. Hm, couldn't Arkane have cut out some of them to make the download smaller?
Cheers,

compressing adpcm is useless...

Duh! I assumed you had uncompressed ;) Would be .ogg files be smaller?
[Which shows I should think before post..bad boy.....bad Tels...]

ADPCM compression ratio sucks, but at least it decompresses quickly and is not CPU intensive. However I agree with Tels, CPU time was hardly an argument back when the Dark engine games (Thief, Shock2) came out (ADPCM compression, too) - about the same time Daikatana showed that MP3 worked fine without affecting the game negatively.
Since Arx plays the audio through the MSACM, it actually shouldn't care whether the RIFFs contain WAV-PCM or a foreign format, as long the codec is installed. I'll go now and experiment with the Lame ACM and (
http://hp.vector.co.jp/authors/VA012897/) Vorbis ACM codecs. Let's see how much further the resource files can be shrunken... ;)

LOL, nice idea :-)
(Sorry about me thinking the WAVs are uncompressed...)

Result of my experiments: doesn't work like expected. RIFFs must contain wav data.
