Ok, makes sense. But for me, it IS in Ubuntu (though universe, not main?):

$ aptitude show libsoxr0

Package: libsoxr0
State: installed
Automatically installed: no
Multi-Arch: same
Version: 0.1.2-1
Priority: optional
Section: universe/libs
Maintainer: Ubuntu Developers <ubuntu-devel-discuss at lists.ubuntu.com>
Architecture: amd64
Uncompressed Size: 215 k
Depends: libc6 (>= 2.14), libgomp1 (>= 4.9)
Breaks: libsoxr0:i386 (!= 0.1.2-1)
Replaces: libsoxr0:i386 (< 0.1.2-1)
Description: High quality 1D sample-rate conversion library

I'm interested in quality more than speed, so speex-float-1 (as worst in
the list) doesn't seem what I'm looking for. Does speex-float-10 compare
favorably to the soxr methods?

Do we know if the PPA* (which I did use for 7) has better methods? Looks
like you may have made those, Luke :-) (Thanks!)
