Hi
You could use [readsf~ 12] to read your file and then several [writesf~ 2] to record, but i guess you want something faster... However, I don't know how readsf~ behaves with 12 tracks/32-bits files (that's somewhat extreme).
this is not a bad idea, i'd say. you can put both, the [readsf~ 12] and the six [writesf~], into an upsampled subpatch to make it faster (using a [block~] object). even if your harddrive wouldn't be able to read or write that fast, you won't have any dropouts in the resulting files, since pd works in a deterministic manner.
since version 0.42, there is a -batch flag, that allows you to run pd as a sound 'renderer at maximum speed, similar to the 'bounce-to-file' option in some DAWs. then you don't even need any [block~] trickery anymore.

Hi everyone.
I want to split a 32-bits 12 tracks audio file (aif) into 6 stereo files (consecutive pairs i.e. 1-2, 3-4, etc.).
I've already tried with [soundfiler], but there seems to be many problems with large files (this one is aprox. 10 minutes lenght) and with 32-bits reading (I listen a kind of quantizing error noise, a sort of dithering-less noise). In fact, I'm thinking of reporting a bug on it, but I'd have to explain which exactly the problem is, and I need some time for that.
Currently, I'm doing this manually with Audacity, but I need it to be automatic and, if possibly, with PD. Any ideas?
Thanks
Ignacio
