Making an Audio DVD

[Pantha]

New to Toast (7.1.2) and attempting to make an Audio DVD. I have converted my AIFF (s) to AAC files to get 52 large audio (radio programs) onto a DVD. The MB change is usually 71MB down to 25MB on the convert. However, when I load these smaller files into Toast to burn a Audio DVD, the files actually become larger - even than the original AIFF's. To check this, I checked DATA CD and put an AAC file - the size was exact. I don't have a clue about what I'm missing here. Any help would be appreciated.

If you make a 'Music DVD', all your audio will be converted to 192 kbps Dolby Digital by default, but you can change the bitrate to a custom value. If your source files are under 192 kbps, then the output size will be larger than your source.

I'm unclear what you mean by an audio DVD. What settings are you using in Toast? You didn't need to do the AAC conversion to make a "Music DVD" because Toast encodes AC-3 audio for those and can make the conversion from the original AIFF files as well as the AAC files.

 

If all you want is to have AAC files burned to a DVD then use the Data window. If you want something that can play on a DVD player then use the Music DVD feature. There's info on how to do this in Toast Help.

 

Maybe you are using the Audio CD setting and thinking those can be burned to DVD media. Audio CDs are uncompressed audio and only work on CD media.

Sorry for the confusion. You're right I meant music DVD. I tried to make the DVD w/out converting to smaller files, in fact the iTunes folder showed a total size of 3.38GB. When I tried to put these same files in Toast, the GB increased to 5.15GB. This is what I can't figure out.

I'm don't know why the file size increased, but it doesn't really matter what size they are before Toast does the AC-3 encoding. Choose Save as Disc Image from the File menu instead of clicking the burn button. Toast will proceed with encoding and authoring the Music DVD and save it as an image file. When it's done you can mount the image file (select it with the Image File setting in the Copy window) and preview it with DVD Player. If all is well you won't have any trouble burning it to a single-layer DVD as long as the disc image is less than 4.38 GB and I'm sure it will be.
