[Need help please ] - Detecting wav's made from m4a (AAC)

Can someone please tell me is there any software which can show me real difference regarding freq. between m4a and .wav files? I've just tried 'spectral frequency' on Audition, but there is no freq. difference between those two on same file. One is m4a other is wav and freq is the same on graph. I'm trying to delete m4a files previously converted to wav. Any suggestions?

You won't find a reliable way to do this, although tools will sometimes catch transcoded files.
