If you are in favor then why, and if you are against then why?

I think it can help music lovers, who want to decide from which areas of the computer there will be a graphic equalizer operation,
and maybe it's also true that high frequency operation in a graphic equalizer,
not directly through the computer's sound card but through a plug-in in the web browser,
can more easily damage the speakers connected to the computer?

And do you think installing a graphic equalizer for others requires permission from copyright holders?
in terms of listening time, is there a change in the frequencies of the music sounds created by the creator if an external graphic equalizer is used?

And if I want to make this offer then where it says that a file must be attached,
so which file image should I attach there?

Thanks in advance.
