[General Topics] Menneisyys:
It was yesterday that I’ve explained how you can listen to Sirius, North America’s one of the two most widely listened-to radio network.

Listening to XM Radio, the other major US-based radio broadcasting company is equally easy on all mobile platforms (Windows Mobile, Symbian, Blackberry, iPhone etc.) Let’s take a look at what we have at our disposal.

1. If you have WMA playback support (currently, Windows Mobile only)

... then, just fire up your mobile browser (any browser capable of invoking external applications: Netfront, Internet Explorer or Opera Mobile; Opera Mini or Thunderhawk will NOT work!) and navigate to http://www.xstreamxm.com/mobile/. There, just fill in your login data, select the channel you’d like to listen to, the bitrate and click Go at the bottom:

after this, you’ll be shown the currently playing song title (the Web page is automatically refreshed every 5 second so the artist / title / album metadata is always kept up-to-date) and the default WMA player (by default, on Windows Mobile, the built-in Windows Media Player) is invoked in the background:

(as with SiriusWM5, the WMA player isn’t passed the metadata info as can be seen in THIS WMP screenshot)

2. Desktop-based transcoding

As XM Radio, unlike Sirius, defaults to high quality streams (and doesn’t require you to pay extra for high-quality streams), if you have a GPRS connection OR want to reduce your data fees, you will want to go for a desktop-based transcoding solution – even if you have a WMA streaming-capable platform (for example, Windows Mobile). The sole reason for this is as follows:

The high-quality WMA stream is broadcast at 64 kbps; the low-quality one at 32 kbps. The latter has really bad sound quality – much worse than that of Sirius. If you need to stream the radio at 32 kbps to your handset (because you’re on GPRS or you MUST reduce your data usage), a transcoder run on your desktop computer can easily transcode the original high-quality 64 kbps stream into a 24 or 32 kbps HE-AAC v2 stream, while keeping the same sound quality (YES, even at 24 kbps!). Similarly, should you want to have access to all your favorite channels in orb only (without having to navigate to another homepage), you might also want to consider “migrating” these channels to Orb. Then, however, you won’t be able to use HE-AAC v2; that is, you can’t reduce the bitrate without a major hit on sound quality.

And, of course, if you have a Symbian or iPhone device (and even the latest Blackberry ones!) currently* not being compatible with streaming WMA, your only choice is desktop-based transcoding – as is the case with listening to Sirius on these platforms.

*: as of 01/06/2008; on Symbian, CorePlayer is supposed to be compatible with WMA but is VERY buggy. The OS itself, while it supports playing back individual WMA files, doesn’t support streaming WMA. Hope the Nokia developers implement both HE-AAC v2 and WMA support in their forthcoming Nokia Internet Radio.

For transcoding, you will need / can to use exactly the same tools as with Sirius, with the only exception that, instead of uSirius, you’ll need to use uXM (current, tested version: 1.0RC2) as the source to either Orb or Winamp running on your desktop.

Configuring uXM, exporting / copying URL’s is done in EXACTLY the same way as with Sirius. The same stands for importing the channel list into Orb and Winamp – you need to exactly the same tricks to make them available for local transcoding. Therefore, please read the Sirius tutorial on all these questions.

Questions, of course, are welcome. Feel free to tell me if you still need a step-by-step tutorial on XM Radio. Again, as everything is done in EXACTLY the same way as with Sirius, I don’t think you’ll need any help.
