How to covert distance to 0-1?

[V972]

This may be something obvious/trivial, but I'm new to the topic and not much of a mathmatician.
In your MFCC + DTW.ipynb exaple the output is 192.489808008.

How can I convert it to 0-1 range to judge it against a similarity threshold?
I will use this to determine if the recording is authentic vs deepfaked voice.
