Re: [chuck-users] WvOut format

Hello George, Your example seems to work fine for me on Windows XP $ chuck --version chuck version: 1.3.4.0 (chimera) microsoft win32 : 32-bit http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ $ cat blerg.ck SinOsc s => Gain g => dac; s.freq(400); g.gain(0.5); g => WvOut w => blackhole; "blerg.wav" => string file; w.wavFilename(file); 1::second => now; w.closeFile(file); // what is the function of the argument here? can WvOut record multiple buffers at once? $ chuck blerg.ck blerg.wav opens fine in VLC, Audacity, and Reaper. michael On Fri, Jun 13, 2014 at 11:39 AM, George Locke wrote:

just going to bump this. chuck can't record a wav! what?!

aifFilename is working, so at least I can record what I'm doing. but srsly, ppl, this is a major bug.

Thanks for the reply. I tried w.closeFile() (w/o the argument), and I tried ending the script with null @=> w; and neither has helped.

Regards, George

This probably isn’t helpful, but I’m using the same versions of ChucK and miniAudicle on OS X and the blerg.wav file looks fine.

I’ve had trouble generating WAV files from miniAudicle in the past, but I think that was when I didn’t call closeFile() explicitly and ChucK never flushed.

I don’t think the argument to closeFile does anything, so I never provide it. :)

Hi,

The output format of WvOut is coming out wrong. Audacity doesn't recognize it as a wav (does not recognize type, suggests import raw), and windows media player rejects it as well. Importing the file into Audacity as raw data works somewhat, but as I'm diagnosing a dc-offset, I need an exact result.

here's some example code:

SinOsc s => Gain g => dac; s.freq(400); g.gain(0.5); g => WvOut w => blackhole; "blerg.wav" => string file; w.wavFilename(file); 1::second => now; w.closeFile(file); // what is the function of the argument here? can WvOut record multiple buffers at once?

I'm not so experienced with chuck but experienced in "normal" computer programming. Running miniAudicle 1.3.1 with chuck 1.3.3.0 on windows 7 pro sp1 (32 bit).

Thanks, George
