Is there a way to isolate hiss from a recording, and then use that isolation to subtract from the original audio?

I have a chain set up, basically I apply maximum treble (inverse RIAA curve) to an audio file, which results in intense hissing and popping from the recording, i then run passive NR over that, and a standard RIAA curve to re-EQ the file, then invert the resulting waveforms. The results are disappointing.

Alternative: If you apply the out of phase (karoke) to a mono recording recorded in stereo, you're left with only pops and hissing. Can I use this to remove these exact sounds from the original?

You can with audacity. The results may vary.

Better to get decent gear

If you're doing this for real, you need to get the iZotope RX plugins.

I know it has a NR where you select a section of buzzing and it removes it from the rest of the audio. Unless you mean something else

I just have some LPs that I recorded to the computer that are good except for the noise. The reason why I'm doing this is because these particular recordings never made it to CD or digital at all, so this is my only chance of preserving them.

Gotcha, you should be able to get decent results with Audacity. But you can totally torrent the iZotope suite and make it sound better as well. I respect what you're doing.

Sound Forge has many audio restoration tools. You could play with them and see the results for your specific problem.
