How to save audio file without direct link playing in chrome or firefox browser?

Question

Browsers

When you click on the button on the page - mp3 audio is played,
A direct link to this mp3 file can only be obtained by listening to traffic (for example, through fiddler)
But this is not an option.
If the browser played this file, is it possible to get it out of the cache somehow? Or force the browser to save all played sounds.

Answer 2

The browser does not save everything in the cache.
You can look for (or try to write) an addon that will save, well, or capture the stream on the OS side.

Answer 3

If the browser has played this file

To protect the playback file from theft, it is cut into pieces and played back sequentially.
