Put the sound files on an Amazon s3 or cloudflare r2 bucket and have the app download them. Maybe put a json file on there too and the app checks if the json has any files which aren't downloaded and if so, it downloads them.

Ans you know that Amazon and Cloudflare are not free, yes ?

I know. But I doubt the total file size is too big. So storage costs will be extremely low. And if they use cloudflare r2, there isn't even any egress fee. The app is already charging $7 per month subscription. Even a single purchase would most likely cover the entire storage cost.
