Volume changes are applied to the exported audio file only

Checking or altering the volume of one or several selected sound objects.

• The volume of the corresponding sound objects can be altered by means of the slider control. ... See also How  to use slider controls. The volume alteration is applied to the corresponding sound objects in the timeline.

• Click on Peak Search to determine the maximum level of all sound objects concerned. After searching the Locator jumps to the location of the maximum volume. The maximum values for every channel are displayed as Peak level or RMS level. The Peak Level ....is the maximum volume level of a sample and relevant for the audio level control. When determining this value, even the tiniest peaks are included so that it has little relevance for evaluating the loudness.  is the decisive factor for a numerically correct audio level. The RMS Level ... is a measure for the highest power in an audio file. This value is a good indicator for the subjective loudness of a sample. For a correct audio level control this RMS level is irrelevant, as its always determined for a period of 50 ms., on the other hand, measures the power and can very well be used for judging the loudness.

The methods for determining the peak level mentioned above consider all volume influences, except for the sum level volume control. When the sum level controls deviate from zero dB, the output signal is modified by this amount. You can still influence the overall sound track volume, i.e. all sound objects in a timeline, with the sum level controls.

• If you want to reset the highest volume to zero, simply click on Normalize (Peak). For individual soundtrack passages this normally does not make sense.
