sox -G "in.wav" -b 16 "out.wav" rate -v 44100 dither -a -s
Hmmm. I actually do have Foobar 2000 also, though I never thought of using it for this work (I also have the SoX plugin mentioned, but I was actually trying to use it for a different purpose). What exactly differs in quality between the methods mentioned?
There are some varying opinions on what is the "best" result for both resampling and for bit depth reduction. For bit depth this has mainly to do with the dither used. Unless something really gross is done, however, (and maybe even then) it is rather unlikely you could hear the difference.For sample rate you can see some visual representations a http://src.infinitewave.ca/Look at the sweep tone conversion using Adobe Audition with filters and say Ableton Live 7. The Audition result is more ideal. There are other interesting displays. As with bit depth reduction, being able to hear a difference does not seem to be an established fact.
It's interesting to see how CEP/Audition which used to get no respect among pros and semi-pros always did a lot of things right, even when more "pro", prestigious, and expensive software like some old releases of Pro Tools didn't even do the basics right.
libsamplerate, written by Erik de Castro Lopo. GPL. The author of libsamplerate requests that you not distribute a binary version of Audacity that links to libsamplerate and also has plug-in support.
EDIT^2: Ah, I think that's the problem:
If you're Windows based and like libsamplerate, you could try srcdrop on the 'Others' page at Rarewares.

If I use SoX from the command line (which I have for de-emphasis, stereo channel flipping, and inverted absolute phase), will this produce the same results as the method you are using?
