“echo cancellation” in Windows audio enhancement
Get rid of Windows Echo Cancellation. That should be buried somewhere in Windows Enhancements.
Windows comes out of the wrapper set for business communications and conferencing no matter what it does to the voice (like a cellphone). It causes no end of problems for people trying to create good theatrical quality.
“Correcting the bass” will throw two different tools against each other. Effect > Equalization whose job it is to suppress far/extreme bass tones, and whichever tool you use to boost the bass tones.
These tools only work perfectly when you start with a plain, clean recording.
