Ubuntu users will have SubMix Audio Editor available at .DEB file format and as Snap package. To write these lines, I tested this program on Ubuntu 18.04 and 20.04, but in the latter the .DEB package has not worked correctly.

As a .DEB package

To start we will download the SubMix Audio Editor .DEB file from the following download link. We will also be able to download the package from a terminal (Ctrl + Alt + T) using wget as follows:

download .deb package from submix audio editor


For this example the name of the downloaded file is'submix_1.0.12_amd64.deb'. Once the download is finished, from the same terminal we can proceed with its installation running the command:

install submix audio editor .deb

sudo dpkg -i submix_1.0.12_amd64.deb

If, as has happened to me, the terminal returns dependencies errors, this can be fixed by installing the missing SubMix dependencies with this other command:

install broken dependencies

sudo apt install -f

With all this, the installation of SubMix Audio Editor will be completed. Now to launch the program we will only have to click on the button Show apps in the Ubuntu Gnome Dock and type the name of the program in the search box. Once the launcher is located, we will only have to click on SubMix to open the program.
