Ever since I began using Audacity, it seems the generate silence menu has need some updating. I’ve posted this in the past. Generating Silence in the beginning of the song shows the correct number I usually use. When I go to the end of the song it will not maintain any number so I have to start from scratch. I have also tried using presets and they do not work. Maybe one of you friendly programmers can update this feature. It doesn’t matter which windows I have used but I am using 11 now.
