Is there a way to figure out the true bit rate of a transcoded audio file?

Lets say you have a 96 kbit mp3 and you Transcode the file into a 320 kbit mp3. How could you programmatically detect the original bit rate? Does one exist or how should I approach this problem? Perhaps an algorithm to detect Generation Loss could be used.
