Still on the road to Cmix ...

PROBLEM 1 - can't record a sound file

I try using the "dd" command from the Sound-HOWTO to record an 8k
sampled sound.  And I do in fact get a file which seems about the
right length.  But then when I try to play it with cat to

Quote:>/dev/audio I get nothing.

I can play other sound files.  I tested the mic, which works.

So I pretend it doesn't matter and plod on.  Which leads to ...

PROBLEM 2 - is sox really converting the files?

I try to use sox (from sunsite.unc.edu - which compiles fine - at
last) to convert this (and other) files into .snd files.  But I
don't know if it's working.  I try several methods from the TIPS
file for the coversion, like:

     sox file.au  -r 11025 -t ub file.snd     and
     sox sox -t ul -r 8012 file.au ...

But when I try to run Cmix on the files (ones created with the mic-
record-file-then-sox and the already-play-file-then-sox method) it
leads to ...

PROBLEM 3 - Cmix still (and may never) work ...

Here are the errors:

============================
input:  151552
name: sample.snd   sr: -0.000000   nchans: -2139062144  class: -
2139062144 sfd[fno] 3
This is an IRCAM soundfile.
Duration of file is -817346451728953199558656.000000 seconds.
---------> Cmix/mix<----------
Opening input file as unit 0
CMIX: malloc ovpeak buffer error

So it looks like the files I'm reading are incorrect ( == Sox
doesn't work ) or something else.

If anyone thinks they can help, I can post some more details about
the commands I used.  But I basically just took the straight from
the files.  If anyone knows commands that do work (for anything)
I'd love to hear about it.

Time for (what's the word?) ... ah yes ... sleep ... precious sleep

Thanks,

Did CMix compile OK? There could be several probs in the compilation
which may explain the problem. For example the use of the %f flag in
fscanf and printf instead of %lf for doubles ... Check that the math.h
header has been included too. Which system do you have? I think I have
cmix lying around on the system here (Sparcstation 10) so I could have a look.

If you use the -V switch then it will tell you exactly what it thinks
the input is and what kind of output it's making.  This is in the man
page.

Hello,

I'd love to hear from anyone who has cmix running under Linux.

  What files do you use.  I've tried dozens.

Thanks,
