Need to update Audio Element links en masse

We moved my website from https://www.thesoundsmith.com/tss/ to https://www.thesoundsmith.com In the process many things broke and needed updating. The automated systems fixed part, but Audio Elements (236 of them) need the links updated. Do you have or know of a search-and-replace that will find these files? None of the WordPress options seem to see the table.

Thanks.
