In my opinion, the short list of commercial software on a PC should include:
Steinberg Wavelab Adobe Audition Sony Soundforge
Wavelab also has very good BWF metadata editing built into it. The last time I checked Soundforge, BWF metadata was not supported. BWF is an important preservation format and standard, and should be a consideration.
Of course, Protools is kind of the industry standard, and is less expensive than it
used to be. But I have little experience with it and I understand that
it is difficult to master. I would think more of an editing or
mastering program would be more appropriate, like Wavelab. I am a
musician, and I have some studio experience from recording my own music,
but I am not an audio engineer by any stretch of the imagination, and my
co-workers generally have less audio background than I do. So
user-friendliness is a big consideration.
