manualy setting output as for .s32 extension

manualy setting output as for .s32 extension

Hi SoX users,

This command works for me:
1) sox --channels 1 --rate 48000 in_signal.wav in_signal.s32

Now, I'd like to change the output filename extension. In that case SoX
can't deduce the format from the extension, so I have to tell it the
details. I tried the following line:
2) sox --bits 32 --channels 1 --encoding signed-integer --rate 48000
in_signal.wav --type raw in_signal.q31

However, I am not getting the same output as using the first command.

What's done wrong in the second command?

Cheers,
Danijel Domazet

You're options you've added apply to the input file, not the output, and
probably don't do what you want.  With a WAV input, you should not
normally need to specify channel count or sample rate unless the file
header is incorrect (it happens).

All you need to do here is say --type s32 before the output file
(instead of raw).

Why are you overriding the number of channels and the sample rate
for a wav file, which already has that information in the wav header?

The option at the beginning of the line (before the input file)
overrdide the specifications for that file. Toy want to put those
specifications before the output file, to tell sox what its format is.
In the wors of the holy manpage,

  sox [global-options] [format-options] infile [format-options] outfile

Don't tell anyone then.
