Chronicall 3.8 introduced the functionality to generate a link that provides a user access to a recording. First, set up the Externally Accessible Address within System Settings > Basic Settings. Typically this will be your Chronicall server IP address and port. You may also add a public address and port (just ensure that port is open and forwarded).
Once the Externally Accessible Address has been configured, go to Cradle to Grave to find a recording. Right click the recording and select the option "Generate External Listen Link".
You will be prompted to enter how many days the link should remain available.
You will then be given the link that can be used to access the recording.
Entering that link into a browser will take you to a simple media player interface and will play the recording.
