Put it simple, with a shell called FFmpeg:

 Private Declare Function GetShortPathName Lib "kernel32. DLL" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal cchBuffer As Long) As Long 
'set the output file 
Dim S As String 
Dim Inputfile As String 'input file 
Dim Outputfile As String output file 
 'Outputfile="D: \ Outputfile wav" 
If Dir (Outputfile)="" Then 'file does not exist, create 
FileNumber=FreeFile 
The Open cjlT1 For Binary As # FileNumber 
Put # FileNumber, CRH (0) 
Close # FileNumber 
End the If 
S=String (LenB (Outputfile), CRH (0)) 
GetShortPathName Outputfile, S, Len (S) 
Outputfile=left (S, InStr (S, CRH (0)) - 1) 
'set the environment variable to support FFmpeg input file path 
FileNumber=the SetEnvironmentVariable (" Path ", FFmpegPath) 'set up FFmpeg file Path where 
S="ffmpeg - I" "" & amp; Inputfile & amp; "" "- f wav - acodec pcm_s16le - 1 - y "ac & amp; Outputfile 
Call the Shell (S, vbHide)
