Probably just that gstreamer is using higher than an 8bit mono 8000Hz signal by default.

I image arecord | aplay could be tuned to give a good output. Looking at 'arecord --help' suggests you can have a lot of control - as with gstreamer.

cheers

I have tiped in Xterminal of N900:
sudo arecord | aplay

then it works as i expected for (N900's mini-jack 3,5 to PC's mini-jack 3,5 = PC with microfone)

But, does it waste the space in internal memory of N900 and should i delete recorded file\files from there after?
Hiz, how can I perform that using windows? any step by step lit guide pls in order to follow (starting from the scratch), TIA

This should work on any computer with a 3.5mm input as all the work is done on the n900s side.

How would you get the n900 to stop transferring the microphone noise to the 3.5mm output?

If you've used a terminal to start the process it should still be running in that terminal. You should send a CTRL+c to quit it.

The correct name of the gst-launch process is "gst-launch-0.10".
So, killall gst-launch-0.10 should do the trick.

no it doesn't.
tried now and there is no answer in terminal..
tried also in a new terminal window but it doesn't kill the process.
i don't have idea of what should be wrong
i've tried the trick also on my linux netbook.... it doesn't work the same... thers something we don't know about gst-launch?
i tried also with this pkill -kill gst-launch but it still doesn't kill the process.
i'm going crazy. i can't belive that the only way to stop
gst-launc ... is by ctrl+c

you can make far more complex pipelines than this but this should provide a proof of concept for you.
This is fu*king awesome when combined with the FM-Transmitter. I now have my own live pirate radio station.
