This page will help you get started with Mastering API.
Mastering is the last step to high-quality audio.
This resource combines the following components into one audio file:
- the synthesized speech of the Script,
- custom media files,
- sound effects
- sound template
On top of that it enhances the audio quality of the whole track.
In order to get a mastered audio file, make sure you requested speech for your script resource first.
