mp3 files bigger than wma files...why?

converting my wma files on my HD, I noticed that the mp3 format is bigger than the wma files.  I thought it was supposed to a compressed format?

I’m using an application to convert the files called the Switch Sound File Converter:

…or maybe I’d just scrap the whole thing and just rip my CD’s into my WMP11 with mp3 format…?

There are a couple of explinations for the size issue. You are probably converting the files into a higher bitrate mp3 than the wma, so the file is bigger. I would just rip the files again using WMP and Mp3 and 192 or 256 kbps bitrate.

And I would usw variable bit rate (VBR), as a good sound/space compromise.

If you have the original CD’s you are better off reripping them.  

I don’t know if WMP uses  a good mp3 encoder.  I suspect not since WMA standard isn’t so hot and Microsoft’s official line is that WMA at 64 kb/s is equal to mp3 at 128 kb/s.  With the better mp3 encoders it is closer to the other way around.  Lame and Helix seem to be the top of the pile and Itunes should be ok too.

A good alternative, still compatible with Clip, would be ogg/vorbis.

actually, I did a dummy test with just one song set in both Mp3 and WMA with 192 kbps…turns out that the MP3 files are at least 1.5 to 2 MB smaller than the WMA files.  interesting.

and is 192 kbps the preferred quality format?  just wondering.

WMP uses the traditional Fronhaufer MP3 codec, as opposed to the newer and preferred LAME version…and doesn’t give you the option of VBR :angry:

I think they use the old version of MP3 to quantify their claim that WMA is better(plus they let you do VBR with their WMA). In a way, it’s kind of Apple-ish:dizzy_face:…they’d prefer you use “their  version”.

 I think 192 is considered a compromise between best sound and smallest file. People with great hearing and higher-grade earphones usually prefer higher rates for better sound quality, but that really can cut down on how many songs fit on your player…so you have to make a decision which way to go.

For a good compromise, I use VBR with 192 kbps as the low end and no set high end.
