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.

Try a lower sample rate ? (-s)

Yes, also with a lower sample rate (1024) the bandwith is too much....
Just to clarify, I use SDR Sharp (SDR#) on a Windows 7 PC (Client side) to connect on the
RTL SDR on the Raspberry Pi (Server side).
If I use my LAN connection no problem at all, but the bandwith is too much for stream over
my Internet Connection (1 Megabit/sec in upload).
Obviously I do not want to stream, for example, Wide FM Broadcasting over the Internet
beacuse the audio bandwith is very high, but I would like to stream over the Internet the
SSB mode (300 Hz to 3400 Hz) where the audio bandwidth is not so much.
So how Can I limit the maxium bandwith by using (Server side) the rtl_tcp command?
I'm pretty sure that with a bandwith of about 3 kHz and a sample rate of 1024 1
Megabit of Internet bandwith can be enought....
I use also the Perseus SDR receiver (by Microtelecom) with it's Server feature (stream
over the Internet) and it works very well, my 1 Megabit of bandwith is enought.

That sounds more along the lines of you wanting to stream the decoded audio rather than
the raw sample data.
You'll probably want to pipe the output of rtl_fm into a streaming source client like
icecast rather than trying to pump rtl_tcp out onto the internet.

Use Virtual Audio Cable software to connect Audio from SDR output to VLC
player configured as a Media Network Stream Server.
