I use Audacity (free) to check the frequency spectrum of a music file. (It also does a good job with showing the file's dynamic range.) I check for the presence of frequency content above 22kHz (the upper limit of a 44.1kHz file). The graph also shows any extraneous noises/signals. For most/all 24/96 files I've downloaded lately, the graphs are very clean and show frequencies extended well beyond 22kHz. With 'fake' hi-res files, there's a very obvious brick wall at 22kHz (or 24kHz, for 48kHz-originated files) and empty space above. As I mentioned before, I haven't seen anything like that for a long time now.
