This is the professional audio RTA software I wrote 20 years ago, a magic tool for catching feedback points, it grabs them accurately every time. Yesterday, there was a discussion about RTA in the group, and I unearthed this ancient artifact, surprisingly it still runs on Windows 11.
Remembering the original intention leads to the ultimate achievement.
To my lost youth!
