wav duraiton returns None

Could you provide a repro ideally with a sample problematic file? I just tried it out and it worked fine on my example.

>>> import sphn
>>> fr = sphn.FileReader("/home/laurent/tmp/20240407-out-3.wav")
>>> fr.duration_sec
59.6
>>> sphn.durations(["/home/laurent/tmp/20240407-out-3.wav"])
[59.6]

(note that durations takes a list of filenames and not a single filename)
