Hi, so I'm going to probably be joining the list of people asking for 64-bit native. My reason isn't "just because" or "aren't all computers since 2007 64-bit capable at this point?" or "Do it for Dale!"
I work with large audio files from time to time and would like to see the 64-bit native so I can take advantage of the fact my computer has 16GB of RAM. I've noticed that my Core I7 isn't much faster than my Core 2 Quad when it comes to opening and processing large audio files, especially when I put them together in multi-track setups where they can hit as much as 3GB (either 96/24 or 192/24). I know there are (usually) better (commercial) apps out there that would handle my workflow better, but there's something I enjoy about the sparseness of Audacity's interface.
Thanks.
