Bandwidth

Hi again.
I would like to stream the RTL SDR over the Internet. My Internet connection is 
1 Megabit in upload (much less than a LAN connection).
Is there a way to decrase or cap the bandwith of rtl_tcp?
In others words: is possible for example limit the audio stream on a bandwith 
of 300 Hz to 3400 Hz?

Thanks.
