There's no fundamental limitation, that's just the way it was coded for
demo purposes.
Going forward, that code will probably become deprecated. In
^/sandbox/online I am working on a new setup for online decoding. See the
example script in egs/rm/s5/local/run_online_decoding.sh. In that version,
it's configurable from the command line. However, it won't do the
subsampling itself, I haven't coded that yet. You'll have to figure that
out yourself. Features from different sampling rates are not comparable
unless you first subsample.
