I have this issue with recording my audio podcasts where i randomly start getting this "clicking" (im not sure clicking is the best way to describe it). It will randomly start after about 10-20 mins and then stop for no apparent reason. Using Audacity on a mid 2012 Macbook Pro with a USB sound card https://www.startech.com/nz/Cards-Adapters/Sound/USB-Audio/Audio-USB-Adapter~ICUSBAUDIOB i tried upgrading the RAM from 4GB to 16GB and still receiving the same issue.
here is an audio sample:
has anyone encountered something similar, what would you recommend?
