Recording Jumpy Audio
I'm getting jumpy audio in my recordings -- would this happen if my CPU
is running at 60%? I have multiple applications running simultaneously: Song Show Plus (Lyric Projection program) PowerPoint Audacity / Sound Forge XP (recording) it's an AMD Athlon X2 4200+ why would I be getting jumpy audio on recording? |

Because you have multiple applications running simultaneously? |

Because you have multiple applications running simultaneously? And/or because there are more choke-points than just CPU utilization. |

Lack of RAM? Fragged hard drive? Other apps or resident utilties you aren't telling us about? |

In other words, shut down things you shouldn't need like IE, Outlook, IM, and etc. Also, it never hurts to scan for viruses, malware, spyware, and etc. To the original poster, all of the above could contribute to swapping. That is, you've allocated more memory than you have RAM, so the OS is constantly swapping chunks of data from RAM to/from virtual memory (which is really just a file on your hard drive). If your OS is busy swapping, the CPU isn't doing much of anything, and your audio application won't be able to grab enough CPU or disk input/output and you'll get "jumpy audio". Note that you can usually tell when the OS is swapping too much because your hard drive light will be flashing madly, or on continuously, even when you don't expect it to be doing so. I assume you're running XP, based on your using "Sound Forge XP". I'd personally recommend at least 512 MB of memory when running XP. Preferably more, especially if you've got a motherboard with integrated graphics that shares system memory. So how much RAM do you have in your box?

This is really incredibly unlikely on today's computers. If you had a machine with very low RAM installed and opened a LOT of programs you might be able to force it. But you wouldn't just get the odd pop. Things would seriously slow down. |

I am running on Windows XP Media Center Edition with only essentials
running: virus scan (AVG Free) and spyware (Windows Defender), the machine has 250GB HDD space and 1GB of RAM. The only apps running are the ones I spoke of earlier. Song Show Plus is intensive on the GeForce 6800 Ultra graphics card because it creates motion 3D backgrounds on the fly. This happens during record. Need anymore information?

Well, turn them off for a start, and pull the plug on your Internet connection. You don't need it during a recording session. The only apps running are the ones I spoke of earlier. Song Show Plus is intensive on the GeForce 6800 Ultra graphics card because it creates motion 3D backgrounds on the fly. I'm afraid that sounds like a strong suspect. Can you turn off the "pretties" while recording? Or drop into a "preview" video mode? |

Can you turn off the "pretties" while recording? Or drop into a "preview" video mode? In fact I would recommend searching the web for a copy of "Enditall". This used to be vital to game players, as it would shut down every unnecessary background task and leave the machine clean for whatever it was you really needed to do. It kind of vanished when machines got quicker, but I'm sure it is still around somewhere. And of course as you say, all that spyware and virus stuff simply has to go - they really slow things down hugely. That needs to be consigned to another machine which can be used as a gateway for any downloads via the Ethernet port. d -- Pearce Consulting http://www.pearce.uk.com |

no, I'm unable to kill the pretty stuff. It's necessary for
performance.
