Or, you could use the ‘reverse’ command, trim the first xxx milliseconds,
and then reverse again. Then you don’t need to know how long the file is.
Or, (and this is the one I’ve always thought was really cool but never
mastered) the ‘silence’ command can trim leading, trailing, and excessive
silence between words. It has ‘thresholds’ that may be of use to eliminate
the trailing pop. But since I’ve never mastered it, I’m just guessing
Veering further off topic…
If somebody really knows there stuff, I suspect the highpass and lowpass
filters could also help produce more intelligible prompts.
