Please support 44.1 khz mp3, this whould be cool 
especially for loom. The Quality of a 22.1 khz mp3 is 
not that good.

Integrating a multi sample rate mixer would make the
resampling for monster.sog/monster.so3 obsolete. In addition
it would enabling the optional use of 44.1 kHz ogg/mp3 CD
tracks (Hence posting this here, since it is the main
advantage of this.).
The required real time resampling best could be done with a
linear interpolation (fast) and a fft lowpass (not that
fast) before downsampling (if this would the case at all)
and after upsampling to the target rate in order to avoid
alias and mirror frequencies. Since this would take a
serious amount of CPU time, this should be an option. You
still should be able doing all at 22050 Hz (or even lower,
if you wish, as 11111 would be enough for FOA, for example),
of course. The extract tool then would need a sort of
--no-resample switch.

Try using OGG/Vorbis instead!  Loom sounds fine here, even
at -q 0 (about 40 kbps !!!)

Hmm, in ZSNES it is possible to change this at runtime,
maybe you can borrow some code there :-)

...and OGGs of course :-)

Note that this would require some major reworking of the
mixer at the current state. Also, we can't just switch to
44khz output, we would have to keep both 44khz and 22khz
possible, since the PocketPC version of ScummVM is already
strained with 22khz audio - 44khz simply would be too much
(talking in terms of processing power).
