Is your feature request related to a problem? Please describe.
When you load a very large file into the audio player, ti takes a long time to load. During this time the user has no idea that the file is still loading.
It would also be nice to a have a single audio interface fro the audio component. Just have the player and add the "drop" function to it. Now we have two interfaces that change when you load a file and thus changes the layout.

Describe the solution you'd like
Add an event to the audio component that the file is loading or triggered when it completes the loading process or add a "rotating" icon for "being busy". Large files are when you do TTS or STT.
