[chuck-users] record audio directly into sndbuf?

My apologies if this question is silly, I'm a bit of a programming
amateur...
I'd like to create a patch wherein I could record a few seconds of
audio from the adc (mic input), then play random segments of that
audio back. Seems simple enough, but I'm having trouble mastering the
art of recording sound in ChucK. Ideally, I'd like to use sndbuf to
store the audio in a temporary buffer, though I'm wondering if my only
option is to use WvOut to write the audio to an actual file.
I'm not even doing very well using WvOut to record... I'd like the
recording to be triggered by a button toggle (or even just triggered
by a normal button with a set recording duration). I think I'm fairly
comfortable with the MAUI button object, but I'm not sure how to
implement triggered recording. I've seen examples that merely set up
an adc => WvOut w => blackhole configuration, then tell the program to
just do this for 5 seconds and then close the file, but I'd like
something where I could have the shred running, and then activate a
recording process when the button is pushed. I've tried implementing
this with a while (button.state()) loop inside of an infinite time
loop, but it usually ends up crashing. I also thought I saw something
about a w.record operation in the ChucK wiki, but I didn't see
anything about this function in the documentation.
Anyway, sorry that this is so unfocused... I'm just not sure how to
even start approaching the problem. Bottom line: can I use sndbuf to
record live audio, and if not, how can I use WvOut to do this?
Thanks,
Matt Diamond
