Is there a way to change the thickness of the line that shows the waveform? I looked all over in preferences, googled, and found nothing.
The reason is that I sometimes want to take screenshots that get resized or included in video. Mpeg has a really hard time faithfully reproducing a one-pixel-thick line, and sometimes people are watching at a lower resolution than what I uploaded, so the lines disappear or are mangled with downsizing.
To be clear: I don’t mean changing the sound or wav data itself, just the way it is displayed.
In GIMP only select the waveform area of the screengrab of Audcaity,
otherwise the numerals are thickened too and become difficult to read when erode is applied.
Usually one application of erode is sufficient IMO.
