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).

Objet : [PD] Split multichannel audio file into stereo pairs

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?
