Hi Charlie,
Kyma could not recognize the file because it has a ".wav" extension when it is really an AIFF-C file and should have ".aif" as the file extension.
In addition, the file is using a non-Apple-defined "codec" that Kyma does not know how to decode. We have added support for it (and a few others that have crept into common usage) for the next update to Kyma, coming soon.
