Hi Afaq, assuming you already know the math behind AM, this is really simple: What you need to transmit is a modulated carrier. So, you just send the audio signal with a DC offset to your USRP and let the USRP tune to the frequency you want to use.
Easiest way would probably just installing GNU Radio and having flow graph: source of the data signal -> add constant (so that all values are positive) -> multiply const (so that all values are |·| < 1) -> USRP Sink Note that in general it's really a bad idea to do amplitude modulation in the 2.4 GHz, because of fading.
