Stream Audio

Nates networkIf you have kept up with the digital media revolution, you probably have a bunch of your favorite music loaded up on a computer, or perhaps like me, spread over several in different parts of the house. If you use iTunes or Windows Media Player, you can easily share these different music libraries on your home network, but this limits on which computers or devices you can actually connect and play them.

In this review, I'll show you ways to enjoy your favorite music all over the house (or around the world) and on any device. Let's start with some basics.

My home network, PCs, and devices are configured to support a variety of streaming strategies.Streaming basics

The basics of streaming audio over a network involve using a media server, a client player, and of course, a network connection (3G, Wi-Fi, etc.) between them. In my case, I use a PC in the basement and one on the top floor (3 stories up) as my media servers. I use my iPod touch or another portable device as my client player. Finally, I use both Wi-Fi and Ethernet cables for my network connections.

Build your own streaming server

Since I'm using multiple PCs and am steaming to more than one mobile device, I use a combination of methods. None of these are really that difficult to get working on a home network using Mac, Windows, or Linux computers. I will share the basic steps and provide the links to more detailed instructions at the end of the article.

Radio Shark 2Radio Shark User InterfaceOne method I used includes a radio tuner—an AM/FM tuner called Radio Shark 2 (RS) connected via USB to a Windows 7 laptop with Linux installed as well. (Griffin Technology has discontinued RS 2, but it is still available through online stores for $30-40.) RS also works with Mac and Windows PCs, allowing you to record and time-shift radio broadcasts. I have a huge library of FM quality hit songs that were recorded using it.

Step 1. Identify a PC or Mac for the server

Your PC or Mac will need plenty of file storage space available, especially if you want to extend your media capabilities to video streaming. For streaming audio around the house as a single stream, a 100Mbps wired LAN connection will work fine for the server, but you might want to consider upgrading to a 1Gbps network card if the machine is going to be doing a lot of other network intensive tasks as well (network backups, video, etc.). If you are planning on using the computer for other purposes (download files, surf the Web, etc.) your stream may experience interruptions. I recommend that you dedicate a second computer as the server (an older one that you don't use much anymore). Most home PCs less than 5 years old will probably work fine. You don't need a super fast CPU, huge amount of RAM memory, or a high-end graphics card for simple streaming.

Step 2. Install encoding hardware/software as required

iTunes SharingAfter setting up your server, you need an audio application to rip, download, or record music. You'll also need a CD drive if you want to rip from your collection. The latest version of the iTunes app for Macs and PCs has a Home Sharing feature that makes it very simple to buy music and consolidate your library to one PC in your house and also provides access to several for playback. You can share music using Windows Media Player (WMP) in a similar manner. I actually do a lot of live recording and use the excellent, free Audacity sound editor ( on my basement studio system. MP3 is a reasonably good standard (there are better ones, but I'll spare the audio techno-babble about digital recording formats.) Suffice it to say, the higher the encoding rate, the better the quality of your recording, and the more space your files will require. FM quality audio has an encoding rate of around 96 kbps, and that is probably adequate for a pool party or exercise tracks. After you have configured a way to record your music (CD drive, line-in audio, etc) and software to encode the data, you need to set up a streaming service if you want to enjoy it elsewhere around the house.

Step 3. Install/configure streaming services

If you use the iTunes or Windows Media Player sharing methods already mentioned, your server is ready to go. However, manually setting up a streaming server is not really that difficult. Now you need some software to stream the files. The free WME (Windows Media Encoder) can do this on Windows based computers and can also send streams directly from an encoding device or through another media server. Personally, I prefer Icecast for my streaming server software.

IceCastIcecast ( is an open source product that can run on a variety of operating systems. Combined with DarkIce (, which streams audio directly from the sound card on Linux, I was able to quickly set up a live stream of the output file from my recorded Radio Shark tuner, which is my encoder device (See links at the end of the article for detailed instructions). Icecast and DarkIce are also available for the Mac. In my case, I run them both on my upstairs PC (as it has really good AM/FM radio reception) to provide the live radio streams. To stream audio from the much larger basement PC library, I use Simplify Media instead (see sidebar). Once your streams are up, it's just a matter of tuning them in on a client.

I use the Icecast admin interface to manage streams.

Step 4. Tune in your stream

FStream: ListeningFstream: Edit a favoriteUse one of the streaming clients mentioned in the sidebar to tune in the streams on your network. In my case, I use FSream (free; on my iPod touch. If you notice that the realtime stream quality is sub-par, try tweaking the stream bitrate parameters and check your network for potential slowdowns or bottlenecks. Some users have mentioned encountering problems using FStream over a 3G connection. It has a setting that will allow you to disable/enable the cell network-I would advise disabling 3G when you are connected to a Wi-Fi network. To add your favorite streams, simply enter the name and URL of the stream you want to listen to (e.g., http://hostname:port) and FStream should pick up the necessary format and bitrate information from the stream. Save your settings and return to the Play screen to play and pause your stream.

FStream will also allow you to record and time shift Internet radio stations (aiff and wav formats only). FStream: RecordThe player can be configured to pause at a spot in the stream, and subsequent play will start again from that point. This can come in handy, for example, if you are listening to a talk show on AM and don't want to miss anything.

Most of what I described does not involve setting up a custom streaming server. The media services and hardware options mentioned in the sidebar all include simple instructions. The client apps are also pretty easy to use. So go stream something and feel free to send me an e-mail or update about your own experiences! I use the Icecast admin interface to manage streams. FStream lets you record and time-shift audio streams, as well as add custom streams.

  • Sonos ZonePlayer S5 ( I was able to get an in-depth presentation of this award-winning product in action at CES and review it on our blogs recently (search for Sonos at This device will allow you to play music (works with WMP and iTunes) from a computer to multiple rooms or pull from Internet services like Pandora. Your music library is completely synced and centrally controlled from your iPod or iPhone.
  • AirPort Express ( This small and unobtrusive network device is much more than a streaming solution. It also allows you to grab music from iTunes and play it in another room on your stereo. Streaming software and apps
