This template was designed to help in the production of multi-voiced audiobooks. It was designed to allow anyone with the share link to update specific records and upload both audio files and pronunciation research. The advantage is that even if you are on a paid plan you can invite collaborators to the base without having to add them as paid users. However, in order to achieve full functionality, there are some items that will need to be updated every time the template is duplicated. If you are on a free plan, you may want to use this stripped-down version: https://www.airtable.com/universe/expAHiXU7gnVoKnnJ/audiobook-multicast-template-for-free-plan
