You can still use Wix Audio Player if you want too, however it can’t be in a repeater.
Although you would be much better suited looking at using Wix Music now seeing as you can’t use a repeater on your page.

Plus, you can customise it a whole lot more than the Wix Audio, so you can have a lot more control over it.
