For working on the soundtrack like background music or some sound effects it's easier to pre-defined and upload to the assets folder and we able to use it via the existing HTML5 Audio, now need always add in after export from the editor
Describe the solution you'd like
Allow to upload audio file formats like webm, mp3, mpeg, ogg
Additional context
For existing was using this way, so quite trouble for those we adding sound.
