There is never a way to guarantee uniqueness with MD5. The more audio content that is checked, the less chance of duplicates. Even checking the whole audio content would not guarantee false duplicates. Checking all data would be really costly on performance. I was exploring the idea of calculating the checksum on a block of data, and then if that is a duplicate re-calculate the checksum by reading more data. Nice idea in concept, to perform the check on a small subset unless necessary, but in reality I can't see how it would work. _______________________________________________ beta mailing list beta@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/beta
