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? |

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. |

Recording Jumpy Audio
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?

Can you turn off the "pretties" while recording? Or drop into a "preview" video mode? |

I think it would be most foolhardy to run any machine without them. They just need to be turned off when appropriate. Along with any Internet connection of course. I find it virtually impossible to actually "turn off" anti virus software and the like. All you can do is disable some of the functionality, but it is still lurking there doing all sorts of unhelpful stuff. d -- Pearce Consulting http://www.pearce.uk.com |

Well, on my machines it turns off sufficiently to be no problem at all while recording audio. I suspect this super-duper graphics program and/or graphics card is the problem anyway. Look at Topic 15 in my CubaseFAQ regarding PCI latency. Could be worth a try. CubaseFAQ www.laurencepayne.co.uk/CubaseFAQ.htm "Possibly the world's least impressive web site": George Perfect |

EndItAll is a prerequisite to recording on my laptop PC (which is the one I use for connection to the internet.) Recording with software that wastes CPU cycles on such frivolous stuff as moving images just seems like asking for trouble. Pure, useless fluff IMHO. Try using a "real" recording application. Some are available for very low cost (like Total Recorder) and some are even free (like Audacity, etc.) |

The internet PC has the firewall/antivirus stuff etc. Of course they could actually be the same computer simply by using different hard drives, or even boot partitions. MrT. |

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

yessir, because what I'm doing is recording the audio of a church
service while displaying lyrics on the projection screens. Everything is all happening on one computer. Laurence Payne wrote: On 30 Jul 2006 08:17:43 -0700, "leetcharmer" wrote: no, I'm unable to kill the pretty stuff. It's necessary for performance. Even when recording? |

nope, nothing silly ... If I wanted to record with another PC, how fast
should it be? Would a 500MHz Celeron take care of business if recording is it's only role?

Would a 500MHz Celeron take care of business if recording is it's only role? More information required for a complete answer. However if you only want 2 simultaneous channels at less than 24/96, and don't require low latency monitoring of the output (zero latency monitoring of the input is no problem) or real time waveform display whilst recording, or any other concurrent processes, then it is *more* than adequate.

My first PC was a 200MHz Pentium with 96MB of RAM. It happily recorded two tracks in Cubase while playing back 10 more. It would have recorded more than two should I have possessed a soundcard capable of multiple inputs. That was Windows 98. Allow some overhead for Windows XP. But, yes, many people were successfully using a 500MHz Celeron as a DAW when that was all there was. Don't try to run XP on less than 256MB though, and 512 is better. |

But fear not, simple recording programs like CD Wave have worked well for me on low end PC's like this. Still, I'd hope it has a bit more RAM than Windows "minimum" requirements.

On a 500 Mhz Celeron, I'd stick with Windows 98SE or even Windows 2000 before I'd attempt XP. The only reason I didn't mention ME is because it's essentially Win98SE with excessive Microsoft bloatware. That and I consider 512 MB of RAM to be the minimum with XP. Anything less than that and the hard drive seems to thrash excessively due to constant swapping, even during booting. I bought one PC with XP and 256MB of RAM. I let it boot exactly once (very slow) before I stuck in another 256 MB DIMM that cost me all of $40. Unfortunately, RAM for an old 500 Mhz Celeron might set you back a bit more, especially if it's something a bit weird (and obsolete) like RAMBUS or something.
