Hey Giulio, I can get your code to work/not crash if you change "wOut.closeFile;" to "wOut.closeFile();". wOut.closeFile refers to the function closeFile, but does not actually call it; the parentheses cause it to be called and the file to actually be closed. SndBuf is causing chuck to crash because its choking on the WAV file, which is not a proper WAV file on disk until its properly closed. In general, I don't think its appropriate that chuck would crash here, but I can fix that pretty easily. Secondly, I recommend looking into the LiSa ugen -- it can accomplish much of what you seem to be attempting here. See http://chuck.stanford.edu/doc/program/ugen_full.html#LiSa for more info. spencer On Sun, Apr 15, 2012 at 1:44 PM, giulio <106ohm@gmail.com> wrote:

Hello, I'm searching information about SndBuff and WvOut (and WvIn?) In the same project I want to record and play sounds but I have some problems...

To explain:

adc => Gain g => WvOut wOut => blackhole;

.5 => g.gain;

SndBuf buf => dac;

"/.../blablabla.wav" => string filename;

filename => wOut.wavFilename;

5::second => now;

wOut.closeFile;

//5::second => now;

//filename => buf.read;

//5::second => now;

me.exit();

...No problem...

adc => Gain g => WvOut wOut => blackhole;

.5 => g.gain;

SndBuf buf => dac;

"/.../blablabla.wav" => string filename;

//filename => wOut.wavFilename;

//5::second => now;

//wOut.closeFile;

//5::second => now;

filename => buf.read;

5::second => now;

me.exit();

...No problem... But

adc => Gain g => WvOut wOut => blackhole;

.5 => g.gain;

SndBuf buf => dac;

"/.../blablabla.wav" => string filename;

filename => wOut.wavFilename;

5::second => now;

wOut.closeFile;

5::second => now;

filename => buf.read;

5::second => now;

me.exit();

...Return:

chuck: ugen_xxx.cpp:2637: void sndbuf_ctrl_read(Chuck_Object*, void*, Chuck_DL_Return*, Chuck_VM_Shred*): Assertion `d->fd == __null' failed.

Why?
