Consider the following scenario:
- You are ripping a CD with Windows Media Player.
- You are compressing the output audio file with the Windows Media Audio Lossless codec.
- You compare the output file size of a file ripped on Windows Vista with the same file from the same CD ripped on Windows 7.
The WMA file generated by Windows Media Player 12 on Windows 7 will be silghtly larger (5-10%) as compared with the file generated from same audio track on Windows Vista.
