Why the soxi is not work?

I compile the sox with the following configuration:

./configure --prefix=/usr --enable-shared --without-magic
make && make install

Now, I can use the sox to edit mp3,mp4 and so on.
But when I type the command:
soxi -t 111.wav
or
soxi -d 111.wav

It's display a help content which is same with "sox --help".
How can I run the command correctly?

help trying to diagnose 0 samples output problem with reverse

I'm using SoX 14.0.0 on a CentOS release 4.5 (Final) machine and when I attempt to reverse an MP3 and write it
as WAV, file, no samples are written.  The only thing in the output is a single WAV (RIFF) header.  When I try
the command with MP3 -> MP3, I get the same behavior but with a single MP3 header in the output.

I tried the same thing on an Ubuntu 8.04.1 machine using the same version of SoX (14.0.0) with the same inputs
and the WAV file is properly written.  It must be a difference between the two environments but I haven't
been able to find from SoX or otherwise diagnose why no samples are written in one case but are in the other.

I've pasted the two test cases below (first is CentOS, second is Ubuntu for comparison).

Also is there a more effective way to truncate a file than using a "reverse trim NNN reverse" pipeline?

Weird.  It's obviously a bug, but I can't reproduce it here (with 14.0.0).  Maybe the bug has since been
fixed---can you try 14.2.0?
If so, and you still see the problem do you see a similar problem if you replace the reverse effect with the
norm effect?

With 14.2.0, there are a couple of other options, e.g.:
  sox infile outfile trim 0 0 NNNN
if the length of infile can be determined from its header, or
  sox infile outfile trim 0 LLLL NNNN
where LLLL is the length of the audio, determined perhaps using `stat'.

Hope this helps,
Rob

Another weird one :)
Please check (and post if necessary) the output of:
  ls -l `which soxi`
and
  ls -l `which sox`

Recording /dev/dsp script output

Dear All -

I have a c script that when executed makes weird sounds
by feeding numerical arrays to /dev/dsp as the output. I'm
on Ubuntu 8.04. I want to record some of these suounds using
sox, like...by feeding the output to sox instead of the speakers.

What's the most efficient way of achieving this? I'll appreciate
any help in this...

thanks,
fadereu

My only guess is to check /tmp has enough disk space to handle to store 
a temporary file that is at least 2 times the size of the uncompressed 
WAV file and that local directory has enough space to store WAV file.  
There is a comment in 14.1.0 ChangeLog that says something about fixing 
ungraceful handling of out of disk space.  That would explain why no 
error messages printed.

First option is the best and 2nd option is pretty good because its 
scanning over audio in a format much more compact then "reverse" does.  
Here is a 3rd option that may or may not be faster then the second 
option above.  With 14.2.0, if you know that all your audio files will 
be at least some minimum size then you can copy over that amount before 
performing reverse and so not have to unreverse so much of the audio 
file.  For example, if audio will always be at least 1 minute:

sox infile.mp3 out.wav trim 0 1:00 : reverse trim NNN reverse

If your program can send its data to stdout, try something like:

  your_program | sox -s -2 -c 1 -r 16000 -t raw - sounds.wav

I am seeing something similar on Fedora 10 box.  Once you find which 
executable is running from above command,  make sure its executing the 
sox you installed.  If not, you can further verify if your seeing the 
same thing I am by running:

ldd /path/to/bin/soxi

Does that show /path/to/soxi is also using similar /path/to/lib/libsox.so?

What was happening on my box is that I installed sox into /usr/local and 
also had /usr/local/lib in my /etc/ld.so.conf.  If I execute 
/usr/bin/sox it would use /usr/local/lib/libsox.so mistakenly.

Fedora is using a snapshot of SoX thats about 2 days before I fixed the 
bug were we were mistakenly using libc getopt().  So /usr/bin/sox was 
half using libc's getopt() and half using libsox.so getopt().

My solution was to remove /usr/local/lib from my ld.so.conf file because 
I don't really need that right now (because most things like with rpath; 
including sox).  If thats not an option then just always specify the 
path to the sox install path when you execute it and hope nothing else 
references /usr/bin/{sox|soxi|play|rec}.

As distributions upgrade to latest SoX, this will not be a probably any 
more.

If your program can send its data to stdout, try something like:

your_program | sox -s -2 -c 1 -r 16000 -t raw - sounds.wav

Thanks....I tried this....but the program plays the sounds (i can hear it) and then exits
as usual, leaving an empty file called sounds.wav

Just to clarify what the program is doing, I'm pasting it below.....

----------------------------------------

#include <math.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/ioctl.h>
#include <linux/soundcard.h>
#include <stdio.h>

void doomsday(int day,unsigned short int foo[]);

int main(void) {
    unsigned short int zap[44100];
    int c; int out; int f=150;
    out=open("/dev/dsp", O_WRONLY);
    c=16;
    ioctl(out, SOUND_PCM_WRITE_BITS, &c);
    c=1;
    ioctl(out,SOUND_PCM_WRITE_CHANNELS, &c);
    c=44100;
    ioctl(out,SOUND_PCM_WRITE_RATE, &c);
    doomsday(f,zap);
    for(c=0;c<4;c++){
        write(out, zap, sizeof(zap));
        }
    close(out);
        return c;
}

void doomsday(int day,unsigned short int foo[])
{
   int n,m,z,c;
   for (m=1;m<1471;m++){
       c=0;
    for(n=1;n<16;n=n++){
          foo[m*n] = 10000*sin(day*2*M_PI*(m*n)/44100);
          }
    z=m*n;
    for (n=16;n<30;n++){
        foo[m*n] = foo[z-c];
        c=c++;
       }
    }
}

In your program, get rid of all the open() calls and ioctl() calls.   
Add "out = 1" at the top to point to stdout.  Recompile and run like 
this (just changed rate option from above since your using 44100):

your_program | sox -t raw -s -2 -r 44100 - sounds.wav
