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)) On Tue, Feb 19, 2013 at 5:21 PM, Alex Lake <alex@digitalmail.com> wrote:
Having a spot of bother with this bit of lua:
result = os.execute(string.format([[sox --norm %s %s.new]], file_to_normalise, file_to_normalise))
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?
