These instructions show you how to purchase and setup a completely self contained Raspberry Pi to broadcast a live audio feed to Broadcastify.com
 
 
 
These instructions have been verified and tested as working on a Raspberry Pi 2 Model B Project Board - 1GB RAM - 900 MHz Quad-Core CPU. 
 
 
 
== Purchase Equipment ==
 
 
 
Raspberry Pi 2 Model B Project Board - 1GB RAM - 900 MHz Quad-Core CPU
 
* http://amzn.to/1Ku3T9Y
 
 
 
Power Supply for Raspberry Pi
 
 
 
* http://amzn.to/1U2r8cD
 
 
 
Memory Card for Raspberry Pi
 
 
 
* http://amzn.to/1U2r8JG

1/8 inch audio cable to connect scanner to USB sound card
 
 
 
* http://amzn.to/1Kor0NH
 
 
 
== Install Raspbian OS ==
 
 
 
All testing and configuration was done using Raspbian
 
 
 
* Follow the instructions here to install the OS on the memory card you purchased:
 
** https://www.raspberrypi.org/documentation/installation/installing-images/README.md
 
 
 
== Install pre-reqs and update raspberry pi to latest version ==
 
 
 
sudo apt-get update
 
sudo apt-get upgrade
 
sudo apt-get install git cmake libusb-1.0-0.dev build-essential lame
 
sudo apt-get install libmp3lame-dev libvorbis-dev libshout-dev libtwolame0 libtwolame-dev
 
sudo reboot
 
 
 
== Configure the Sound Card ==
 
 
 
* Plug your scanner's headphone jack into the mic jack on the USB sound card dongle
 
* Start alsamixer
 
 
 
pi@raspberrypi:~# alsamixer
 
 
 
* press F6, choose the "USB Headphone Set" entry
 
* press your tab key to select the "Capture" device volume control
 
* use your "up arrow" key to adjust the level to it's lowest level possible (6)
 
* press escape to exist alsamixer
 
* run the following command to save the volume settings
 
 
sudo alsactl store
 
 
 
== Two Choices of Software to Broadcast ==
 
 
 
We recommend the darkice install and configuration method
 
 
 
=== Method 1: Darkice Install and Configuration (Recommended) ===
 
 
 
* download the precompiled version of darkice
 
wget http://s.broadcastify.com/darkice/darkice_bcfy_v01.tar.gz
 
 
 
* uncompress the files
 
tar zxvf darkice_bcfy_v01.tar.gz
 
 
 
* move the files to the proper places and make sure they are executable
 
sudo mv darkice /usr/bin
 
sudo mv darkice1 /etc/init.d
 
sudo mv darkice.cfg /etc/darkice1.cfg    <--- note the "1" in the /etc/darkice1.cfg you are copying to
 
 
 
* Edit the /etc/darkice1.cfg file to match your settings, including the sound card you are using, your feed server, mount, password, and description, then exit and save the file
 
 
 
sudo nano /etc/darkice1.cfg
 
 
 
* Enable the feed to start broadcasting at boot
 
 
 
sudo update-rc.d darkice1 defaults
 
 
 
* Start your feed
 
 
 
sudo service darkice1 start
 
 
 
=== Method 2: Ezstream Install and Configuration ===
 
 
 
sudo apt-get install ezstream
 
 
 
Create the following configuration file at '''/etc/ezstream_bcfy.xml''' and replace with your mount, password, and stream name.  If you plan on having multiple streams make sure and create a separate named configuration file (i.e.'/etc/ezstream_bcfy2.xml) for each stream and reference accordingly in your command script below.
 
 
 
<ezstream>
 
    <url>http://audio#.broadcastify.com:80/your_mount</url>
 
    <sourcepassword>your_source_password</sourcepassword>
 
    <format>MP3</format>
 
    <filename>stdin</filename>
 
    <svrinfoname>Stream Name</svrinfoname>
 
    <svrinfourl>http://www.broadcastify.com</svrinfourl>
 
    <svrinfogenre>Scanner</svrinfogenre>
 
    <svrinfodescription></svrinfodescription>
 
    <svrinfobitrate>16</svrinfobitrate>
 
    <svrinfochannels>1</svrinfochannels>
 
    <svrinfosamplerate>22050</svrinfosamplerate>
 
    <svrinfopublic>0</svrinfopublic>
 
</ezstream>
 
 
 
* Run this command to start the sound card broadcast
 
 
 
arecord -f dat -c 1 -D hw:1,0 | \
 
/usr/bin/lame -r -s 48 --resample 22.05 -m m -b 16 --cbr --lowpass 4 - - | \
 
/usr/bin/ezstream -q -c /etc/ezstream_bcfy1.xml > /var/log/bcfy1.log 2>&1 &
 
 
 
Note: very little volume will be needed from your scanner - adjust the levels as appropriate for a good sounding feed.
