Why does the .m4a file size differ???

Hi,

I need to convert a bunch of .wma files for my itunes library.

I've chosen m4a over mp3 because I've heard the sound quality is better.

However, when I convert a 192kbit file using EasyWMA - the output is just 151kbit. When I tell iTunes (windows) to do the conversion, I get the selected 192kbit.

Why does the size and bitrate differ?

I know that this isn't an answer to your question but why don't you just use iTunes since it seems to do a better job?

I do. But im just curious and want to know why the conversion is not done in the same way

FYI, it's not wise to convert a lossy file format (WMA) to another lossy format (m4a). Your files are not going to sound very good.

Perhaps not - but because itunes and iphone doesn't support wma - I have to.
