Hello everyone.
I am making a script that is supposed to mix together 2 separate versions
of the same files. So far so good. Now it has to be able to do this in a
batch of all files in one folder, to an output file, a mixed file.
The idea is to have samples called *sweep1.wav be combined with the files
called *sweep2.wav. So far my script is combining *only* one specific *"sweep1"
file*, the last in my list *(which is number 3)*, with one the correct
"sweep2" file.
*Here´s the script so far:*
-------------------------
for file in ./*sweep1*
do
for file2 in ./*sweep2*
do
out=COMBINED
sox -V4 -m -v 1 $file -v 1 $file2 $file-$out.wav
done
done
--------------------------
As you may see I have put -v 1 in front of both of the files. If I do not,
the two files will be mixed with a linear gain of 0.5, I guess half of its
linear gain value.
Hope someone can see my error here. The output should be the combination of
the two first files with the same file name tokens. The method is "mix",
-m.

Change the script so that instead of
sox -V4 -m -v 1 $file -v 1 $file2 $file-$out.wav
it issues
echo sox -V4 -m -v 1 $file -v 1 $file2 $file-$out.wav
(if that's appropriate for the script language concerned) and find out
what the
set of sox commands it actually issues are. If it only issues one
command then
you need to fix the script - not a sox problem.
Is it by any chance seeing the combined file (whose name will start with
$file)
as one of the files seen by the outer loop? Maybe it would be better to
put the
new files in a different folder.

This is most probably a shell scripting problem
which has nothing to do with SoX.

You are combining every *sweep1* file with every *sweep2* file,
overwriting the output over and over again. Of course the last wins.

Okay. I see. I'm doing it on a Mac with bash in terminal. Do I need to do a "for each" and an "echo" or something? Or perhaps specify the thing more? I'm new to bash and Sox.
Thanks for any help!

You need to find out what commands the script is issuing. Using echo
might help.
I have never used bash so I have no idea precisely what is happening.
Maybe just one sox command is being issued, processing all the files at
once.
Maybe multiple sox commands are being issued but are also processing as
input the files produced by previous sox commands. I can't tell. But
a good start would be to see what the for loops are actually doing.

Thanks for your help. I looked into sox now but the issue seems to be in
the for loop in bash. I am getting help on stackexchange for that, lots of
folks to help out.
Thanks again!
