Thank you for your reply. After much searching and analyzing I have found that the problem lay with the audio reproduction software, the VLC media player, so NCH's fine VideoPad editor V12 remains unsullied. I hope it remains serviceable as I am very disappointed in the price increases which I paid, $US29.95 for V12 9/20/2022 - and an upate in 2023 forVideoPad Video Editor Home Edition $US39.95 (up 50%) and now in 2024, not paid and unlikely to do so at $59.99, another 50% increase. But I suspect that Borate is an AI generated response and therefore nobody really cares.
