ALSA UDP streaming app

This application streams sound form one linux input device to another devices output using UDP/IP communication. Works with Raspberry Pi.

How to run

Clone/Download this repository to your devices and build it, by typing in terminal/console (on both linux devices):

git clone https://github.com/markondej/udp_stream
cd udp_stream
make

ALSA libraries are required, so install it before building application. Ie. on Debian this can be done by:

sudo apt install libasound2-dev

Then run service on device with sound input:

./service 0.0.0.0 6734 plughw:1,0 44100 1 16

Notice:

0.0.0.0 is an IP address on which service will be available, this can be set to any of device's address ie. 192.168.0.64 (0.0.0.0 means binding on all available interfaces with IP address assigned)
6734 is an UDP port on which service is listening
plughw:1,0 is ALSA input device which should be used, use 'arecord -l' to find out which devices are available
44100 is sampling rate
1 states only one channel will be used
16 is number of bits per sample

On the output device type:

./client 192.168.0.64 6734 hw:1,0

Notice:

192.168.0.64 is an IP address of device with running service
6734 is UDP port on which service is listening
hw:1,0 is ALSA output device which should be used, use 'aplay -l' to find out which devices are available
