Hello!
Following the discussion in the thread about 'High Definition Audio' (http://forums.sbooth.org/viewtopic.php?f=12&t=2080) I rewrote an Applescript that I used to do sample rate conversion (src) with and I thought I could share it. It's a simple frontend to some open source tools. I have now included the latest version of 'Secret Rapid Code' which is the best open source converter available and added a Readme.
So, if you're interested, you can download it. The link is: http://www.mediafire.com/?zzkr5h9jhxt
It's 22 MB because I included all the sources to make it easier to compile the binaries if you'd like to do that (I included some instructions as well).
sha1 is:
