Hello guys!
I
want to use my N900 connected trough usb to PC like microphone.

Is it possible?

I want use it in TeamSpeak/Skype/ and other voice software.

Thanks!

Re: N900 like micr

Maybe we can use gstreamer on N900 to capture and send data to Linux PC where gstreamer receives audio and routes it to alsa aloop driver (http://www.alsa-project.org/main/ind...x:Module-aloop) for use in Skype or any other application.

Re: N900 like micr

Here are commands and setup instructions for using N900 mic as Skype mic input over USB networking.

After USB network setup:

host's IP address is 192.168.2.14
n900's IP address is 192.168.2.15

Following commands should work over wireless too.

I get good quality and barely acceptable latency with this:

Code:

host$ sudo modprobe snd-aloop # load loopback kernel module



host$ gst-launch-0.10 -v tcpserversrc host=192.168.2.14 port=9999 ! audio/mpeg, channels=1, rate=48000, mpegversion=1, layer=2 ! ffdec_mp3 ! alsasink device=hw:1,0,0 sync=false



n900$ gst-launch -v pulsesrc ! audio/x-raw-int, rate=48000, channels=1, signed=true, width=16, depth=16, endianness=1234 ! ffenc_mp2 bitrate=320000 ! tcpclientsink host=192.168.2.14 port=9999

Test the setup by routing N900 mic input to Linux sound card:

Code:

host$ gst-launch-0.10 -v alsasrc device=hw:1,1 ! audio/x-raw-int, rate=48000, channels=1, signed=true, width=16, depth=16, endianness=1234 ! queue ! audioconvert ! alsasink device=hw:0,0

Talk into N900 mic and if you can hear yourself setup should work with Skype and other apps probably.

Start Skype and select Loopback hw:1,1 for microphone input.

hw:0... is internal sound card and hw:1... is loopback sound card on my Linux system.

I tested with wired Nokia headset that came with N900.

I have ArchLinux on host.

For windows? any chance?

It could be possible with GStreamer for Windows (http://code.google.com/p/ossbuild/) and Virtual Audio Cable (http://software.muzychenko.net/eng/vac.htm).
