sound equalizer

[Moltke]

please i would like to know how to change sound equalizer similar to this?

That app seems to be a dell app for its own products. On linux you could try puseaudio-equalizer and pulseffects:

Code:

sudo apt-get install pulse-equalizer

Code:

sudo apt-get install pulseffetcs

https://launchpad.net/ubuntu/bionic/+pac...-equalizer

Hope this helps!
