It may be that Microsoft Updates introduced this problem. When System Audio if turned off the problem does not occur. Imagine I may have to uninstall and re-install Camtasia Studio 9.1.2, but will wait for Tech Support to evaluate and respond.īoth Snagit and Camstasia Studio exhibit background noise when System Audio is recorded. Waiting to see if CamStudioDiag.txt and DxDiag.txt reports added to my Techsmith Support Ticket provide any insights for TechSmith. Old recordings, if re-edited and saved, sound also normal and have no buzzing.Īt Command Prompt, using Windows 10 System File Checker, no errors found. If recording mic only, no buzzing is introduced. Upon reboot, buzzing is introduced into new screen recordings when system audio and mic is used, or when only system audio is used. Perhaps this note is a memory leak caused by too long a screen recording (>54mins.) and, as perhaps file size may have been too large for Camtasia Studio, this caused the system crash. Perhaps I damaged some TBD software element.ĭxDiag report noted a Fault bucket, type 5, RADAR_PRE_LEAK_64.
Buzzing is introduced when making new screen recordings with system audio.This is not mic interference related.If recording mic only, the buzzing sound is not heard in the produced recording.
