Yep, it does. There are options to add in
/etc/sipxpbx/freeswitch/conf/autoload_configs/shout.conf.xml as

<param name="encode-brate" value="32"/>
<param name="encode-resample" value="44100"/>
<param name="encode-quality" value="0"/>

(support added with http://jira.freeswitch.org/browse/FS-1231)

didn't play with them, please report back with findings
