One of the most convenient features of PLAYDECK (from the Plus version upwards) is the automatic adjustment of the playback volume of each clip. This means that the viewer will perceive them as equally loud.
Please set your desired Target Loudness as well as the True Peak Level. PLAYDECK will now ensure that the maximum level is not exceeded even during peaks.
As a rule, you should leave the Loudness Range value as it is.
You can set separate values for output volume or input sensitivity for the two stereo channels of all outputs and inputs.
You can also output the two playlist outputs as a mono summed signal and mute the output via the Windows standard audio device. The latter is useful to avoid slightly shifted audio playback from the video output card if it is inadvertently selected as the Windows default audio device additionally.
