For example, SCSI drives are not supported by iTunes and a blank disc needs to be in the drive before you click the Burn CD button in iTunes. Roxio will release an update, 5.0.1, to fix these minor problems. A. iTunes is primarily an MP3 jukebox application that provides basic CD burning. If all you want to do is make very basic audio CDs, and you are running Mac OS 9.1, and you have a supported drive, iTunes may be all you need. On the other hand, Toast was designed as a professional CD mastering tool.
Most recording studios use Toast to master their production CDs.
Toast builds on the limited capabilities of iTunes and provides support for more Macs, more OS versions, more CD formats, and more CD recorders than iTunes. We timed how long it would take to make a backup copy of a store-bought CD with both Toast and iTunes. Toast burned a backup copy of the same CD in only 9 minutes and 17 seconds. Toast was more than twice as fast as iTunes. A CD copied using Toast will sound just as good as the original.
