Optimising your PC for Audio on Windows XP
|
• Tuning Tips for Windows XP (Steps 1 to 5 can all be done from the Control panel) |
| 1. The first thing to do is to
change the Processor Scheduling to 'background
Services'. This will improve the performance of ASIO
drivers on the PC. Go to System > Advanced > Performance settings > Advanced > Processor Scheduling to background Services 2. Next thing is to switch off Power Schemes. If these are on then your CPU may not be running at full speed all of the time, which may be the cause of problems with audio performance. Go to Power Options > change the scheme to 'always on'. You should see all settings change to 'never'. 3. Then you should disable all system sounds. The windows alert sounds popping up during a recording session may interrupt the audio stream. Go to Sounds and Audio devices > Sounds > Sound scheme to 'No Sounds' 4. Set the transfer mode for all devices to 'DMA if Available' Open device manager, expand the IDE ATA/ATAPI controllers category then double click on each one of the IDE channels, under the 'Advanced settings' tab make sure that transfer mode is set to 'DMA if Available' and not 'PIO only'. 5. Disable Windows Firewall. This should be set to ?off? and all network/internet connections` anti virus and spyware detection software should be disabled during recording to avoid any interference. If you are still having issues, disable all networking in the device manager. |
| • Windows Scheduled tasks |
| Some utilities that
have been installed on your computer will may have added
tasks to the windows Scheduled Task list, not all
installers will tell you before adding tasks to this
list and if any of these cut in while you are making
music/recording they can interrupt the audio
stream. Open the Scheduled Tasks window (Start/Programs/Accessories/System Tools/) double click on any tasks in the list and make sure they are not scheduled to cut in when you are using your computer for audio. |
| • Windows Task List |
| Once you have been through all of
the above stages in the Windows control panel, you
should then take a look at all the Processes running on
your computer in the windows Task
manager. Open task manager by holding down CTL + ALT + DEL Then select the Processes Tab (It's recommended to do this after booting up, and before you've opened any programs manually.) Sort the processes by User name (Click on the heading for this column) and check through the processes labeled with your user name. If you then go to www.answersthatwork.com and go to the task list page, you can then check the processes running on your computer against their task list info to see what they actually are and disable any tasks that you feel are unnecessary. |
| • PCI Latency |
| If you have been through all
of the above and you are still having trouble with
clicks and pops in your audio stream, something in your
system may be hogging the PCI bus and you should check
the PCI latency timer values of the devices on your
computers PCI bus. Click here for more information about PCI latency timer values and how to change them. |
