In Ubuntu 12.04 I installed sox with this command:

sudo apt-get install sox

Now if I use this command:

sox message.wav message.flac rate 16k

I get this:

bash: /usr/local/bin/sox: No such file or directory

If I use this command:

sox --version

I get this:

bash: /usr/local/bin/sox: No such file or directory

But if I use this command:

which sox

I get this:

/usr/bin/sox

So now what do I have to do in order to convert WAV to FLAC using sox?

Your usage seems to be correct, the real question is why you can't run sox. –  washbow Mar 4 '13 at 16:30

It looks like your shell has cached the location of sox for some reason. You can work around the problem by giving the full path of the command:

/usr/bin/sox message.wav message.flac rate 16k

Try hash -r to clear your shell's command cache. Also try alias | grep sox in case you have an alias set to a bad location.

The problem got solved with a restart.But now I am getting this: john@john-System-Product-Name:~$ sox message.wav message.flac rate 16k sox WARN wav: Premature EOF on .wav input file sox WARN rate: rate clipped 4355 samples; decrease volume? sox WARN sox: `message.flac' output clipped 2309 samples; decrease volume? The conversion is getting done though. –  Manojit Ghosh Mar 5 '13 at 12:53
