• Possible Cause 1: Input levels are too “hot,” causing clipping or input
distortion. Make sure you have the proper signal levels coming from your
source audio device, and lower the output if necessary.The incoming levels
may be easily viewed from the Audiophile USB Control Panel peak meters.
• Possible Cause 2: Your application software may not have the proper
audio buffer sizes set. Each software application handles this differently, but
typically there is somewhere in the software’s setup to set the size of the
playback and recording buffers used by the application. Some applications
also require you to run a calibration (sometimes called “profiling”) the first
time you use the software with a new audio interface. For instance, if the
clicks are present when using Cakewalk SONAR, then try to run SONAR's
Wave Profiler.
• Possible Cause 3: Some accelerated graphics cards use excessive
amounts of system bandwidth, preventing the recording buffer of an audio
interface from keeping up with demand. This can cause clicks in the
recording. Reducing or turning off the graphics card’s graphics acceleration
feature often resolves this problem. In Windows, the level of graphics
acceleration is accessed from Start | Settings | Control Panel | System |
Performance | Graphics.
