Changeset 1708

Message:

Add a context menu with some predefined values and a spinbox for direct entry of custom values.

And display the values in dB. The calculation is currently fixed on the values of the DICE, for more flexibility the dbus-interface needs an extension. Then the range and the definition of 0 dB could be device-dependant.
