I don’t remember SndBuf ever being multichannel. In fact, there is a SndBuf2 just for stereo. That UG can be chucked to dac for auto stereo, or allows access to .chan(#) for arbitrary routing. SndBuf mixes everything down to mono, and I fear there is no support for > 2 channels via SndBuf.

If my statements above are true, then Someone could do us all a cool favor by making a SndBufN chug.

Dear chuckians?

This is bizarre? I was sure I have done this in the past, but it isn?t working and now I?m a bit flummoxed?. Any ideas here?

PS: I?m trying to route channels 0 and 1 of a stereo .wav file to dac channels 2 and 3. Should be simple. So why doesn?t this work??

I realize that I could just spit it into mono files? but why? I thought SndBuf supported up to 8 channels.

?

SndBuf sb;

//read in stereo sound file
"snd/squeakies/bell_4.wav" => sb.read;

//works - and routes channel 0 of sb to dac.chan(3)
sb.chan(0) => dac.chan(2);

//doesn't work - claims NullPointerException
sb.chan(1) => dac.chan(3);

1::minute => now;

?ss

Hi Scott,

Are you on Windows? Did you specify the -in and -out flags? When I last tested it, the non-ASIO build doesn't support multi-channel audio. Also, the -dac flag needs an extra character before the number.

If you start the ASIO build of ChucK like this, it works.
chuckasio --dac_3 --adc3 --in8 --out8 test.ck

Here, 3 is the audio device number. See http://electro-music.com/forum/topic-69370.htmlhttp://electro-music.com/forum/topic-69370.html

Hope this helps,

        Doug
