I used GoldWave back when I did this mix.
Of course, if I was still into remixing and editing music the way I used to, I'd be using Adobe Audition 1.5 (formerly known as Cool Edit Pro, or something like that)
These days, I'm using Adobe Audition 1.5 to remaster my vinyl records transferred digitally to my computer. They sound much nicer now.
