Can it do the reverse? The analysis of the current frequency is the hard part, not the speeding up and down, which can be done with sox already:
sox 440Hz.wav 432Hz.wav pitch -31

For example, to tune a file to 440hz:
zretune 440 input.wav output.wav

or even more convenient, when dealing with equal temperament:

zretune 60 in.wav out.wav

to tune to the frequency of midi key 60, which is the middle C.
