Hi everybody
Audacity is well-known and very good.
From an older PC, I have a licence for Goldwave. It's a general purpose audio editor, with a lot of sound effects, including modules convenient for vinyl repairing, it looks rather complete in my view (pop/click-, hiss-, noise- removal, high & low- pass filters...).
It can also manage file splitting (using cue points).
However, I recently discovered VinylStudio, and it does look great. GW can do more or less the same, but without VS lookup function which is just appealing. I'm going to try it out.
Concerning phono pre-amp, I am using the phono input of a Denon AVR, and the record output of the same AVR :-), then up to the PC.
