Choose the file, the quality you want for it, the output folder and click 'go' button. That's all you have to do to resize audio files using MP3Resizer.
MP3Resizer Express is extremely useful if you don't want to waste space in your HD and, more important, in your portable media player.
Remember that most audio files out there are in an extemely high quality and you can reduce the size while keeping the quality in good condition.
