A twenty-second delay for recording a forty-second clip is a pretty bad efficiency ratio. Modern software loves to use additional processes so I wasn’t surprised when the busiest process wasn’t SoundRec.exe , but the verbosely named “RuntimeBroker.exe <Microsoft.WindowsSoundRecorder>”. All that scanning, for nothing?
