Is it possible to resample an MP3 file to a different rate (44.1) without doing a reencode? I have a few MP3 files that are at 48 and I need to switch 'em to 44.1, and I don't want to have to reencode my files to do so, as I'll lose quality. The source files are at CBR 320 and at 48kHz. Can this be done?

The current way I'm doing it is using the following command:

lame -b 320 -q 0 --resample 44.1 input.mp3 output.mp3

Is there a better way to do this?
