Core Audio Format = safe ?

Clouds

I noticed that Gamesalad happily imports and can use Core Audio Format (.caf) files (and keeps them as .caf files rather than converting them to 'music'/m4a or 'sound'/ogg files).

Is this likely to cause issues when it comes to running the app on iOs/iPhone/iPad . . . . or are .caf files safe to use ?

Good question - here's an educated guess:

Probably depends, because .caf files are containers and not an encoding format, which means they could contain different sorts of encoded files, theoretically. So if the .caf file contains an encoded audio format that iOS has no decoder for, it could cause problems, even though CAF is an Apple format. Most .cafs are AIFF or MP3, though, which should be played back without problems.

Cheers,
Moritz

Cheers for the reply MoritzPGKatz, yes that all makes sense, I'll avoid them for the moment (or convert them to something GameSalad compatible).

It's Lisa, the singer (one of two singers actually) from the band 'The Loose Salute' - the image is from a video I made for them, here you go (link below) you can take a close to see if she really does look like your ex . . . !

.caf files can improve things. The format is uncompressed so plays immediately and can be lighter for GS as it doesn't have to worry about uncompressing it .. the downside to it, it takes up a lot more space in file size within GS.

If a .caf file contains an MP3 (as Moritz, above, suggests it can) then it would be compressed. (?)

Yes: as I said, CAF is a container format.
Apart from uncompressed PCM, it can also contain MPEG type formats.

Here's the previous video I did for them:

Veeeery nice. Professional stuff. I really like the band too; before I google them, have they any CDs out?

Clouds

"have they any CDs out?"

Sure, they have a couple of albums (or is it three) out.

Thanks Tynan: excellent stuff, I'll definitely be buying one of their CDs for my collection.
