Now THAT does run sox - at least it shows the output of sox on the screen... Thanks. Not sure, though, that --norm does quite what I was hoping! Alex
Here an example of how I execute sox from lua, to get the recording length : https://github.com/Star2Billing/newfies-dialer/blob/master/lua/libs/texttosp...
You might need something like this :
function simple_command(command) -- local file = assert(io.popen(command, 'r')) local output = file:read('*all') file:close() return output end
res = simple_command(string.format([[sox --norm %s %s.new]], file_to_normalise, file_to_normalise))

Having a spot of bother with this bit of lua:

It's returning -1. I believe freeswitch is running as root and that the sox file is in that location and is runnable.
Any ideas?
