Does anyone know the file format of a .snd file? I have some .snd
files that were recorded with a NeXTStation that I would like to
convert to something I can use on my own machine. Here's what I know
so far [from the head of Quest_for_the_Holy_Grail.snd :-]:
0000: 2E736E64 0000001C 00052432 00000001 .snd......$2....
0010: 00001F4C 00000001 00000000 7BFC72F8 ...L........{|rx
Magic #: 0x2E736E64 ".snd" (4 bytes)
?: 0x0000001C (4 bytes)
Size of sound sample: 0x00052432 (4 bytes)
?: 0x00000001 0x00001F4C 0x00000001 0x00000000 (16 bytes)
Sound sample: 0x7BFC72F8 ... ... (336946 bytes)
Anyone care to fill in the question marks and explain the encoding scheme
for the body of the sound. As this is for educational use, maybe you could
just snip a bit out of your on-line manual. I would do it myself but some
buffoon here at the University decided that no more guest login on the NeXT
can be allowed... (AND because it is so close to the end of the semester
no new accounts should be passed out. What a load of...)
Send E-Mail and I will summarize to the net. No NeXTmail, only ASCII, for
the above reason. ;-)
Thanks for your time,

(336946 bytes) Format one is SND_FORMAT_MULAW_8, the final question is how is MULAW_8 different from ULAW_8 as used on the Suns? I know that there is a difference because the ULAW2MySoundFormat translator did not produce anything that sounded close to correct... Anyone know and willing to quickly explain it? As before, I will gladly accept email and summarize in a brief posting as above. Thanks for your time, Loren J.
