I tried the scripts supplied above - and actually none of them did work on my systems. Anybody that really succeeded with these scripts?
The wget command by emilianoheyns seems to work on my Linux desktop. I would guess that on a Windows machine, you need to check at least that wget is installed and maybe change "wget" to "wget.exe" if using PowerShell.
The original script is a bit problematic because it has all individual file paths hard-coded in it. If any new files have appeared after it was created, you would need to manually find them and then add them to the script. The regex approach is more elegant even though it has the small annoyance that it also downloads other stuff than just the sound files.
