Converts from linear energy to decibels (audio).
Converts from linear energy to decibels (audio). This can be used to implement volume sliders that behave as expected (since volume isn't linear). Example:
::
# "Slider" refers to a node that inherits Range such as HSlider or VSlider.
# Its range must be configured to go from 0 to 1.
# Change the bus name if you'd like to change the volume of a specific bus only.
AudioServer.set_bus_volume_db(AudioServer.get_bus_index("Master"), linear2db($Slider.value))
