I use the following command to process MP3 to WAV file conversion.
switch.exe -convert -settings .wav pcm16 8000 1 -outfolder %outdir% -overwrite ALWAYS "%outdir%\%infilename%" -exit
Using the -exit leaves a process running called switch.exe in Task Manager. When launched from an automated process, a switch.exe process remains running each time. I've seen over 10 switch.exe processes running in task manager.
Without the -exit, all processes are released correctly on exit. Has anyone else experienced this behaviour?
