Unhandled exception: System.DivideByZeroException

[DougPHynes]

Hello EMU Community,

I ran EMU 6.2 on a large directory of WAV files (generated from an Wildlife Acoustics SM4BAT-FS):

PS C:\Users\HynesD> Set-Location -Path "C:\Users\HynesD\emu\emu_6.2.0"
PS C:\Users\HynesD\emu\emu_6.2.0> .\emu.exe metadata --no-checksum E:\acousticData\raw\bats\\**\*.wav -F CSV -C -O C:\Users\HynesD\emu\emuOutput\bats.csv

It seemed to output a CSV okay, but I got the message below.
I did notice, after the fact, that included in my directory were a few seemingly corrupt files, with no discernable durations.
Maybe that caused the message, and all is actually well?
