Thanks for the confirmation the new treatment helped, Floyd.

Yes, I did read that post and some of the options. I think because you mentioned Studio 1, I sort of skimmed past the post because I work with Sonar; even though the methods would crossover.

The Melodyne approach seemed closest to what I was familiar with, so I gave it a go.

I think I did improve in hearing sibilant sounds.

The problem now is I hear it in ALL my previous songs whereas before ignorance was BLISSSSSSSSSSS. LOL

Thanks again for the feedback.

Cheers.
