OK, the easy test is over. Time for the difficult one. This one is just about bit-depth, not lossy compression.

These files are longer, I wanted a full reference of dynamic ranges, since that's supposed to be what 24-bit gains over 16.

Two of the files above are full 24-bit. The other three are dithered down to 16-bit with noise shaping. The 8 least significant bits are 0-filled so the files are all the same size. You challenge is to tell me which two files are 24-bit.

Before you had a 25% chance of guessing right, now it's only 10%. But if 24-bit really is that large of an improvement it shouldn't be difficult. smile
