Let the upsampling - remonetization begin!!!
Very rare to source undithered 192/24 files.
Ear training schools will be needed.
12 mb mp3 to a 280 mb 192/24 bit files sound the same to most untrained ears. Heck some pay top dollar for vinyl cut from poorly dithered 44.1/16 bit files. One never knows the true source file unless it comes off the console - and most studios multitrack at 48k with poor summing. Sorry to crash the party - just speaking from the other side of the glass.
