Previous WordPress Editor The audio player has a dedicated template, but in this new editor, when we add an audio file, the browser uses the audio player to play the file, this is a very bad case.

Hi,
The biggest problem is the player of google chrome which offers the download (sic).
The musicians are delighted :)

For visual reference:
The Classic editor relied on the [audio] shortcode. This shortcode triggers a custom audio player that appears consistently across all browsers:

Gutenberg instead relies on the standard <audio> HTML tag to embed audio. Each browser displays this a little differently, and Chrome does indeed include a "Download" link in an associated menu (behind the vertical ellipsis):
_Chrome_

_Firefox_

_Safari_

Also worth noting while we discuss: the old [audio] shortcode is still available for use via the shortcode block:

An idea for a more modern audio player :
(and with a playlist: Cover on the right and name of the tracks on the left)

Optional cover & link, customizable color of the "play" arrow ...
I will associate this issue with the Playlist issue: https://github.com/WordPress/gutenberg/issues/805
