Noteburner

NoteBurner is magic but it doesn't perform any new tricks. The revolution is that NoteBurner is automated. Start process with a Virtual CD-RW, it burns any music files on the virtual CD, rips tracks on the virtual CD, encodes tracks onto any unprotected music files such as MP3, WAV, M4A. It can repeat this audio converting procedure until your whole music collection is done.
Since the virtual CD emulates your computer RAM and hard disk as erasable CD-RW drive (Virtual CD-RW), the converting speed is faster than any other programs which use recording as one of the core converting tricks.
