Hello,
Why does PD generate noise?
Let me explain: I'm currently using the onboard soundcard (ASUS motherboard with a c-media audiocard). I don't experience any unwanted noise when I use Cool Edit Pro, Windows Media Player, etc. for wave playback. But the instant that I open PD...i get noise! (a buzz and a hum somewhere around 800 hz). I close PD, the noise goes away. I open PD, the noise comes back.
Is PD generating this buzz? or are the drivers? or is the c-media DSP?
If I buy a MOTU 828 (or some other interface) will that noise go away?
If I use ASIO drivers instead of the standard drivers, will that noise go away?
p.s.: I'm using Windows XP.
Many thanks. Dave Sabine
I have had similar experience with a certain setup. It had on-board sound and speakers build into the monitor. As soon as PD started it generated som kind of weak buzzing sound (like static) which changed if i held down a mouse button. I believe that the culprit was either the drivers or the soundcard. On that computer I could also hear modem traffic, btw (very faint though). I have only experienced it on this single machine.
I don't thing PD is actually _generating_ the buzzing sound.

Hi,
At work we have one LCD display which somehow generates noise that actually seems to be interference from the image displayed, and some of it bleeds through the audio outputs, although very faintly. I'm mentioning it because I noticed it first while launching PD, and it seemed to be the large white area in the empty patch that came up that was generating the noise. If that makes any sense.

Why does PD generate noise?
The noise may be caused because pd is not able to keep up with the sound card. Regular buffer underruns sounds can sound like a steady tone. Try starting with a larger number of frags..., e.g.
pd -frags 15

No idea.
Good luck, andy
