Ah, I need to try this when I get home! If I can use SndBuf to actually read stereo files, then no need for jack or VirtualAudioCable or any such thing. I did download Jack, but it seemed like a mess. There were all kinds of things you needed (pieces of mingnu or whatever), so I won't bother unless I really need it.

1. You need to read a file into the buffer before chucking the channels to the dac.

// BEGIN CODE SndBuf s; s.read("mystereosound.wav") s.chan(1) => dac.right; s.chan(0) => dac.left; // END CODE

2. I haven't tried Virtual Audio Cable, but I've used Jack (http://jackaudio.org/) to do this kind of thing. You might want to give it a try.

3. I'm not sure what you mean by "that". I think the two questions you've asked can be addressed without using the file io goodies.

I want to have chuck read a stereo input file. The only way I've been able to process stereo is to first separate each stereo file into two mono files, then manipulate these separately with two SndBuf instances.

1. Is there another way to do this? I've tried: SndBuf s; s.chan(1) => dac.right; s.chan(0) => dac.left;

This compiles fine, but crashes with null pointer exception when it is run.

2. VIrtual Audio Cable for windows? THis is software that allows you to route output of any program to input of others. WHen I install it, winamp can find and apparently use one of these virtual cables as output, however how might one get chuck to use the input side of this cable?

3. I've heard of some sort of new file io class; would that help?

Thanx much... -- Rich

I think SndBuf is always outputting in mono, but can read a stereo sample. Try the following: SndBuf s_left, s_right; "/home/atte/music/samples/seq/beats/bar_matched/dnb1.wav" => s_left.read; "/home/atte/music/samples/seq/beats/bar_matched/dnb1.wav" => s_right.read; 0 => s_left.channel; // not needed 1 => s_right.channel; s_left => dac.left; s_right => dac.right; s_left.length() => now; -- Atte http://atte.dk http://modlys.dk _______________________________________________ chuck-users mailing list chuck-users@lists.cs.princeton.edu https://lists.cs.princeton.edu/mailman/listinfo/chuck-users
