[SoX-users] Window length for the stats effect

[Jan <vo...@ge...>]

Hi,

I am writing a shell script that uses sox to make some measurements of the levels. Here is an example:

*lame source* | sox --type raw --rate 44100 --encoding floating-point -b 32 -c 1  -  -n trim 0 5:00 stats -w 1.0 : 2>&1

If I remove the "-w 1.0", everything is fine. With it I get this:

sox FAIL stats: invalid option `-w'
sox FAIL stats: usage: [-b bits|-x bits|-s scale] [-w window-time]

I can't make heads or tails out of this. 

Thanks for any help!
Jan
