I've been using Sound Forge since 2005(ish). Can't recall the year exactly, but it's been a total joy. I started on Windows when people still used Windows, and then moved to Mac years ago when my company shifted us all over. I can fly around on Sound Forge as if it were a part of me. It is fantastic software.
I'm sad to see it fall apart and go away. I will miss it. Anyone have any recommendations for similar Mac programs? Adobe Audition? I use Studio One 5 for multitracking, so I guess I could just use that if I have to.
