Re: [chuck-users] WvOut format (Spencer Salazar)

Ok, I just tried this on Windoze 8.1 Pro. Newest installer from The ChucK/mini download page. Ran both command line and miniAudicle. Audacity, QuickTime player, iTunes, and my own sndview (DOSBox based sound/spectrum viewer, First created in 1988, migrated forward since) all read and play the created file without complaint. Only GoldWave gave me a warning that the internal size didn't match the header, but opened it and played it fine. Prc Sent from my iPad :-)

George,

This has been a source of problems the past few versions as we have refactored WvOut to optimize real-time performance. That being said I can't reproduce this bug on Windows XP with chuck 1.3.3.0 or 1.3.4.0. I can't test on Windows 7 at the moment, but I may be able to try that a bit later.

A few ideas-

- Try an absolute path for the file path, or use me.dir(): me.dir() + "/blerg.wav" => string file; There might be some strange file permissions issues happening if the destination file isn't in a directory chuck can write to.

- Try updating to the latest version of chuck/mini (1.3.4.0).

- Do you get the same results in the command line version of chuck as in miniAudicle?

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.

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.

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

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
