Answer 1

I'm paraphrasing from this answer

The following commands will install PulseEffects on your computer. As you are adding a PPA, you should also know how to remove that PPA.

First, install the program for (eventual) PPA removal:

sudo apt install ppa-purge

Secondly, add the PPA to your system, do an APT update, and then install PulseEffects

sudo add-apt-repository ppa:mikhailnov/pulseeffects -y
sudo apt update
sudo apt install pulseeffects

Finally, should you need to remove PulseEffects:

sudo ppa-purge ppa:mikhailnov/pulseeffects
