Hi Rojben,
No, there is no program that can remove these sounds. But AOMrecord disables the system sounds if the corresponding setting is on. Anyway there are some programs that don’t use system sounds. Instead they produce their own noise. These cannot be filtered because their sound is not registered as system sound. E.g. all MS Office programs use this type of sound and therefore will not disturb your recordings.

Best regards and have a nice weekend
