Hello,
Thanks for the nice comment.
Yes, you can export your sound library from a computer with all the audio files and import it on an other computer.
To do that, you need to go in the "Sounds library" view by clicking the musical note on top
Then you can select the sound library that you want to export and click on the export button on the bottom
You'll need to specify a path and it will create folder with your sound library and all the sounds
That folder can be copied on another computer
Then you will have to use the "Import" button.
And specify the json file in the copied folder.
Note : You can't currently just export a category or an item, it is the whole library
