Misleading...Audio Converter LE
 
Okay, I'm checking for updates after installing XP, and I come across the Media Player Bonus Pack with Audio Converter.
It says,

"Convert your mp3s to wma format (windows media audio or something like that) and save space on your hard drive."

Well, I've got about 8 gigs of mp3s with only 2 gigs left on the drive, so I think I'll see what this is all about. What a crock! I used it on a few files just to see what it would do. Okay, so it cut the file size in half. Then I open the file and realized why. It just cut the bit rate in half. Boy, what a great new format. Just a little misleading if you ask me.

I'm no fan of Windows Media, but to be fair you really should know that it's a little more complicated than that. It's a very common mistake to assume that bitrates are comparable across codecs. Certainly, you stilll see lots of "experts" claim DTS is superior to DD simply because of its higher bit rates.

WMA being much newer than MP3 probably implements some of the more advanced techniques for data reduction. It's well within reason that the latest version of WMA is able to double the efficiency of MP3. That is, it can produce a file of equivalent sound quality to MP3 at half the bitrate.

Unfortunately, when you're converting from MP3 to WMA, the sound won't be as good as if you encoded from the original WAV straight to WMA. There's bound to be some artifacts from the transcoding.

Of course, this is all theoretical since I've never used WMA and never will.

Yeah, I figured I was jumping to conclusions. Thanks for clearing it up though. If the sound quality is equal, I might consider converting some, but I seriously doubt it.

Microsoft decided to add drm into wma. I think I'll stick with mp3's.

IIRC, this is the story with MP3+ (basically v2 of MP3). It's a cool idea, but I don't really see MP3+ catching on since MP3 is so popular now and it would be hard to get people to move over.
