Description

a Rasperry Pi-based appliance that broadcasts video or audio via DILC servers.



Materials

A. Audio Streaming

  * Raspberry Pi (Model B)
    
  * SD Card with installed Raspbian "Wheezy" OS (Operating System)

         
  * USB Sound Card
    


  * Audio Computer Microphone
    
  * USB Micro Cable with Power Brick (5 Volts, 2 Amperes)
         
  * Ethernet Cable 
    

B. For Programming

  *PC Monitor 
  *USB Keyboard
  *USB Mouse
  *VGA to HDMI Cable or RCA Cable




Procedure

A. Installing and Running the Rasbian Wheezy OS (Operating System)

  • Insert the SD Card into your Raspberry Pi and write the disk image file using the installed win32 Disk Imager.


B. Setting Static IP


C.Programming for the Audio Streaming

After installing and running the OS of your Raspberry Pi, you are now ready to program the audio streaming.

Open the LX Terminal,


  • Install PulseAudio and these preference GUI with the command


sudo apt-get install pulseaudio

sudo apt-get paprefs

sudo reboot


  • After the system being rebooted, next thing to do is to edit and add the following lines in the file /etc/pulse/daemon.conf by these command


sudo nano /etc/pulse/daemon.conf


lines:

resample-method = ffmpeg

default-sample-rate = 44100

alternate-sample-rate = 44100


after these save and exit by Ctrl+o and Ctrl+x


  • To make the Raspberry Pi audio server appearing automatically in your "Sound Setting" on every client (PC) and the server (raspberry Pi).


sudo sed -i 's/AVAHI_DAEMON_DETECT_LOCAL=1/AVAHI_DAEMON_DETECT_LOCAL=0/g' /etc/default/avahi-daemon


  • Activate the network feature of PulseAudio on both client and server.


paprefs


For the server mark the following boxes


Network Server -Enable network access to local sound devices

Network Server -Allow other machines on the LAN to discover local sound devices

Network Server -Don't require authentication


For the client you want to stream from the server (Raspberry Pi)


Network Access -Make discoverable PulseAudio network sound devices available locally


  • Reboot the both server and the client by:


sudo reboot


After the system rebooted the Sound Setting should appear like these:


  • To check if the streaming is working plug in the Computer Audio Microphone in the USB Sound card and start to talk. note that there will be a delay of 1000ms-2000ms.
