Problem recording the output of Csound in QuteCsound

Hi,

I'm trying to record the output of a midi controlled instrument to a file.  I'm basically playing and trying to record the performance to disk. QuteCsound has a recording function which allows me to do this easily but the output file is terribly distorted.  I've tried changing buffer sizes with no luck.  Any ideas what might be happening and how to solve this?
I'm on an intel mac running os 10.5.7.  Csound version 5.10.


Cheers,

Nicolas

I haven't used QuteCsounds output to disk option but I use fout all
the time in my instruments. It's very simple to use.

Hola Nicolás,

This sounds like a bug... Can you try using 0dbfs = 0 to see if it
works properly?

One thing I've noticed is that currently QuteCsound will wrap clipped
values, making clipping a lot worse than it originally was... Is this
what you are seeing?

Cheers,
Andrés

Hola Andres,

Here's what's happening:  I'm using a midi controlled instrument so somewhere inside the code I have the following statement:
iamp   ampmidi  15000
If I try to record the output like this it results in a distorted file.
Now if I set 0dbfs = 1  and change the above statement to iamp ampmidi 1 (or some value between 0 and 1 excluding 0) it records fine with no distortion.  Any other setup results in a distorted file.

If I try to write 0dbfs = 0 like you suggested I get the followng error message.....  bad value for 0dbfs: must be positive.
Let me know if you'd like me to send you the code so you can try it. 

Cheers,

Nicolás

Hola,

Sorry,I meant 0dbfs = 1... You would also need to adjust all the
amplitudes in your orc... I'll try this when I get the chance.

Cheers,
Andrés
