Can you tell the difference between mp3 and wav files? Below you will see several different samples. Each contains an original uncompressed wav, a 128kbit mp3, and a 384kbit mp3 file. Play each with headphones or on your best sound system and then click "show" to reveal which is which. See if you can tell the difference.

Note: samples are randomized each time the page is refreshed so you can take the test multiple times.
