OCTA-CAPTURE, UA-1010: SYMPTOM: Pops, Clicks and Dropouts

Tags: driver,pop,sound,click,noise,crash,buffer,drop,dropout,crackle

Pops, clicks and dropouts are often signs of a buffer size issue. There are generally two buffer settings within a computer audio system:

  • The buffer setting in your audio interface (i.e. the OCTA-CAPTURE) adjusts the INTERFACE's access to the computer's RAM (buffer).
  • The buffer setting in your recording software (e.g. Sonar, Pro Tools, Logic, etc) adjusts the SOFTWARE's access to the computer's RAM.

These two buffer settings are independent of each other; however, each affect the performance of your computer audio system.

Be sure to check the Audio Buffer Size setting within the OCTA-CAPTURE Control Panel if there are noise issues and/or dropouts. Increase the buffer size until the problem goes away. The following procedure will guide you through these steps:


  1. Select "Control Panel" from Windows' Start menu.
  2. Double-click on the OCTA-CAPTURE icon to open the OCTA-CAPTURE Control Panel
  3. In the OCTA-CAPTURE Control Panel, select "Driver Settings" from the Driver menu—the Audio Buffer Size window appears.
  4. Increase the Buffer Size and then click "Apply".

Mac OS X

  1. In the Applications folder, open the OCTA-CAPTURE Control Panel.
  2. Select "Driver Settings" from the OCTA-CAPTURE Control Panel menu—the Audio Buffer Size window appears.
  3. Increase the Buffer Size and then click "Apply".

If the noise and/or dropouts continue, adjust the buffer setting within your software.
: As each manufacturer's software differs from version to version, please refer to the software's current manual or online help for the proper buffer size adjustment procedures.
