Steve Harris has a "Decimator" in his swh-plugins that reduces sample  
rate : "Decimates (reduces the effective sample rate), and reduces the  
bit depth of the input signal".
There's also a "Smooth Decimator"

As for increasing sample rate Ardour (at least) automagically  
upsamples imported sounds to match the sample rate of the project.  
Alternatively you could use sndfile-resample or sox to do that.
