Question about SDIF files

Post by tmrolls » Sun Mar 20, 2016 5:18 pm

I have a quick question on reading SDIF files. I am using Audiosculpt and Spear to create files, but when I try to read files in Bach created with Audiosculpt, Max hangs or crashes. Most files I use created in Spear read fine, unless they are very long. Is this expected behavior? Or am I doing something wrong in creating the SDIF files in Audioscult. I much prefer working in Audiosculpt because of it's editing tools, but I suppose I can work around that. I'm using Max 7.2.1, Bach. 7.8.1, and Cage 3.1.

Regards,
Tim

Hi Tim,

can you send us one of such SDIF files that do not open on your machine?
cage SDIF modules are unfortunately expected to be rather slow, and I suspect that some of your "hang" might just be long computational time. Indeed cage is a library made solely by abstractions, and it made sense to us, in that context, to develop abstraction-made SDIF helpers. We are aware that because of this choice those modules are very slow (if you open them, they some sort of matrioska-made abstractions). We might be tackling this problem with native C code in some other context.

Please feel free to send me the SDIF files causing issues at danieleghisi@bachproject.net.
I'll do my best to look into it.

Regards,
Daniele
