simulated tape loops

[Tyler <programmer651@comcast.net>]

Hello! Is this my original idea, or has it been done before? If it has 
been done before, I would 
like to hear from some people. Simulated tape loops. You take a digital 
audio file that was converted from a 
tape (therefore it still has tape noise, and is lower quality than a 
made-digital sound), and you use 
audio software to loop the tape-sampled digital recording, simulating a 
tape loop. Is this 
my original idea?
