[78-L] Removing hiss - yet another idea

[John Wright]

When I'm restoring I start with a stereo file and sometimes see noise in 
one channel and not in the other, which is useful, cut'n'paste the good 
bit.

Now,

"the main problem with all noise reduction systems: how do you 
distinguish between signal and noise? "


That got me thinking. If you have two 78s of the same recording the 
music is the same, but the noise is different, and likely different all 
the way through.

So has someone invented a computer program that compares the two 
recordings and just saves the sound that is COMMON to both? i.e. the 
music?

Let me have a share in the new patent, please :o))
