[Csnd] Can't understand this

From these lines:

itabz ftgen 0,0,1024,7,0,50,1,50,0,924,0
a1 oscil 5000,30,itabz
outs a1,a1


I would expect a sound whose characteristics repeat 30 times/s, but when i render them, there is some sort of pulse that happens about once a second.

Since I was trying to isolate the problem, i've commented out all the other lines in the instrument, so these are the exact lines i'm playing.

I really have no idea of why this happens, has anyone?

Hi,
Your table is close to a pulse... And with your example I do hear a
pulse 30 times per second...

Cheers,
Andrés

    I tried out your piece of code and I also get a pulse about thirty times a second. It's really quiet, since my laptop doesn't have good response at 30Hz, but it's there.  If I bump the frequency in a1 to 300, it becomes a very audible buzz.

Thanks guys, you are right. I've just tried to render it to an mp3 instead of
listening to it as csound was running, and it plays right. I guess my
computer is just too slow.

I don't think it is likely to be slow; but you might need to adjust your 
buffer
settings (-b and -B), for instance:

csound  ...   -B4096 -b1024

esp. if you are on Windows and not using ASIO.
