What I mean is that if the file is binary identical, it means that my original high resolution file was upsampled from a low resolution one. If you use straightforward and simple upsampling and downsampling algorithm you can have - file A 44.1 Khz -> file B upsampled to 88.2 Khz from file A -> file C downsampled to 44.1 from file B -> file D upsampled to 88.2 from file C I guess file B and D are binary identical. It means that even if you never heard of file A existence, you can reliably suppose that file B is an upsampled one ... -- nicolas75 ------------------------------------------------------------------------ nicolas75's Profile: http://forums.slimdevices.com/member.php?userid=15823 View this thread: http://forums.slimdevices.com/showthread.php?t=74688 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
