I'm looking to get into documentary filmmaking, and I'm wondering what the best software solution is for mixing audio. I am going to be getting a Zoom H4n soon, so that's how I'll be recording sound. For video, I'm either shooting at 24p or at another frame rate that I then conform to 24p for slowdown. I have Final Cut Studio, which does offer audio mixing controls, but I'm not sure if it's powerful enough to be an end-all solution..? How about GarageBand, Logic 9, Audacity, etc?
