:: This script converts audio files to a simple basic wav format.
:: This allows a comparison tool (https://github.com/David-Maisonave/SoundComparer2) to be able to 
:: compare audio files to see if they're duplicates fairly accurately even if the original files are in different formats or file types.
:: Requirements:
::				ffmpeg.exe

:: Change the following path to point to ffmpeg.exe if ffmpeg.exe is not in the environmental path
set FFMPEG="ffmpeg.exe"
:: Change the following folder name to the desired target folder to send the converted files
set WorkingPath=Conversions

:: Ussing ffmpeg, convert audio file to *.wav type file with AudioCodec=PCM, Stream=1, Channel=Mono, Quality=Lossless, SampleRate=8k, BitDepth=8
