Toast 7 Used Sd2d For Audi Cd Images?

Question

I am backing up my collection of store bought Audio Cds as disk images with Toast Titanium 7 (new) and I noticed that toast is saving the images not as a .IMG or .TOAST files but a with a .SD2F extension?? No idea why and it seems that this file format "sound designer 2" is old and is forked?? and should not be used. Thanks toast! - I've just archive 60 Cds in this apparently useless old format!!

 

Can anyone tell me why toast is using this format, how to make it save the images as .img or .toast files. I do still have toast 6 still installed. (on a positive note it really speedy and creates a full size image of the CD in 2.5 mins)

 

Thanks

I'm not sure why this bothers you. Control click on the .sd2f file in the Finder and choose Mount It from the contextual menu and it appears the same as the original CD on your desktop. Also, sd2f files can be read in audio editing applications. You can open the file in iTunes without mounting it if you want to import the CD as a single track (some people do this with live concerts).

It works fine, I can mount it with toast and even itunes will play the tracks. I'm wondering why they choose this format not a .img .dmg .iso or .toast and also what is a sound designer 2 file ?? When I google for it I get this

 

From http://filext.com/detaillist.php?extdetail=SD2F

Sound Designer is a Macintosh application. Sound Designer II files store all sound samples in the data fork and all sound parameters in the resource fork. Sound Designer II was discontinued several years ago, and is no longer available. Quicktime should play the files. The Sd2f designation it typically the Macintosh creator code. The file extension is more often seen as .SD2.

 

I don't want to end up with 100 or so not compatible image files in a couple of years.

The reason they use sound designer format, and not img or toast is that in actuallity those 2 can only be used for data. CDDA format (redbook audio format) is not data but one long audio track with a table of contents of where each track starts. The SD2 format is not a disc image but is one audio track comparable to aiff. The differance is that it can also hold a table of contents that toast reconizes and amzingly can mount a virtual cd of it

while sd2 may have been a Mac application that is no longer around, the file format is a cross platform, industry standard Audio CD format. You will find that just about any quality Windows audio program can read sd2 files, and even though the program is not around, people have extended sd2 to 64 bit sd2 allowing for file sizes larger than 2 GB. I have been able to record 96 kHz, 24 bit audio files in the sd2 format (sd64). Jam used to save all its disk images in sd2 with all its awesome info and then dispatch it to toast for burning.
