[Freeswitch-users] Running sox from within lua

[Areski]

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/texttospeech.lua#L113

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))
