Audacity It works and its free.
I guess you didn’t read though the thread. It turned out the editor was not the problem.
Also... I’m not so sure Audacity would work for recording, say, a webinar, if Windows’ “Stereo Mix” has been disabled by a user or by a Windows update or upgrade. Maybe Audacity has a tool to correct that? Those might be interesting bits of info. (pun intended) for those who use Audacity, or are contemplating doing so. (Yeah, I’m asking someone who uses Audacity to check it out.)
