How to test container field for "sound" file?

What check can a script perform on a container field to determine if it contains a sound file? My immediate need is for PC file formats, but a cross-platform check would be useful.

Thanks in advance for any help.

If it is a file, you can check its extension, looking at GetAsText ( ContainerField ).

Actually, I had tried that ... since it works on image files. But all I got was "?" in return. Maybe there was an error in the script step, but my workaround on the whole Sound Record issue eliminated my need to check.

Thanks, anyway, for your response.

all I got was "?" in return.

That's because a sound recording is not a file.
