Hi Graham and all,
Yes. The patch you are using is the mono version. Search for rec2.ck in the examples, it is stereo.
Wait, the rec2.ck isn't there anymore.
The convention is to have a .L and a .R file. You can combine these together into a stereo track in Audacity or ecasound or some other audio editor or processor. This did show up on the mailing list around November 05. Try searching the archives for more details.
Here is the link. We are definitely going to improve things so we can record to multi-channel. By the way, 1.2.0.5 supports real-time multi-channel audio. A multi-channel sndbuf/WvOut are on the way, but probably won't be in the next release. Stay tuned. https://lists.cs.princeton.edu/pipermail/chuck-users/2005-October/000050.htm... Best, Ge!
