How big is "big"? 100 lines? 1,000? 1,000,000?

Your command takes a line number and a color, and applies that color to
that one line, yes? If so, why loop at all?
As written, the code applies the color to the same line over and over
for the number of lines in the field.
Maybe pLineNum could contain a list of line numbers?
If so, iterate through it rather than through the field, since chances
are you're only setting the color of a subset of all lines in the field.
Locking the screen first will speed that up even more.
But faster still will likely be to follow Brian's guidance on
styledText. With that you probably don't even want to lock the field,
since all the changes are done in a variable outside the field, and the
variable is set back into the field only once at the end.
But once we understand what's needed, the speed difference may not
matter much. Or it might. It depends on how big "big" is.
If you want to clear everything at once:
set the backgroundColor of line 1 to -1 of fld "audioList" to empty
All this is just guessing, though. I'm not really sure what this
handler should do.
