That sort of work would happen outside of asterisk using tools like 'sox', and 'audacity'.
For example, with sox you can concatenate files like so: sox 1-for-am-2-for-pm.gsm thanks-for-calling-today.gsm output.gsm Normalization would happen outside of Asterisk, I'm not sure how it would be done from the command line with sox, though it's easy to do in Audacity (Effect -> Normalize).
