Does anyone know how to burn CD quality music to a disk image or DVD from iTunes?
Add the files to a playlist, select the playlist and click Burn.
Select Data CD/DVD. The CD/DVD will be identical in size, quality, format and all other info, to what you have in iTunes.
The objective is to backup all of my iTunes purchases in one place.
The easiest way to backup iTunes is to copy the entire \Music\iTunes\ folder to an external drive.
I want the backup music to be in CD quality sound, this usually aiff format.
To be accurate an audio CD does not contain AIFF files. They are PCM in audio format. AIFF (and WAV) is simply PCM as stored on a computer.
Putting AIFF files on a CD is not the same as creating an audio CD.
If they are AAC now and you burn to an audio CD, the quality will NOT be improved over the AAC. You will simply be making the files 5x-10x larger. Also, later reimporting the audio CD as AAC, the quality will again be reduced.
So I get to repeat my question, can I burn or save music from iTunes to a disc image in the aiff format?
I would not recommend this at all for your purpose (backup). It would be a waste of time.
Burn the files to a *Data CD/DVD* and they will be identical in quality, size, all info, when you re-add then back to iTunes.
A data CD will hold ~120 songs and a Data DVD will hold ~1000 songs. The songs are exactly as on your computer.
