User Manual

The commands for changing volume are as follows:
 To change volume in increments of 1dB, do one of the following:
–
Clip > Audio > Increase Audio Level 1dB (Option-Command-Equals)
–
Clip > Audio > Decrease Audio Level 1dB (Option-Command-Minus)
 To change volume in increments of 3dB, do one of the following:
–
Clip > Audio > Increase Audio Level 3dB (Option-Shift-Equals)
–
Clip > Audio > Decrease Audio Level 3dB (Option-Shift-Minus)
Normalize Audio Volume Command
The Normalize Audio Levels command automatically adjusts the level of clips to a specific
target level, and you can choose the method used to analyze each audio clip’s levels to
determine how to normalize each clip’s volume. Options include a variety of loudness
normalization algorithms specific to various international standards, which are useful for
balancing the perceived overall loudness of several clips to one another, regardless of transient
levels throughout each clip. You can also do Peak normalization, with options for both Sample
Peak and True Peak.
The various loudness options are designed to analyze an audio signal based on its perceived
loudness to the listener, which results in a more accurate automatic balancing of different clips’
audio levels to one another, regardless of transient peaks occurring throughout different clips.
The target peak meter now uses the BS.1774 standard for measuring maximum “true peak,”
which means that this meter is capable of measuring “inter-sample peaks,” rather than only the
peaks at each sample of a waveform. However, you still have the option to measure Sample
Peak, which is the previous method of measuring the actual peak of the samples in a media file.
The change made by the Normalize Audio Volume command is only a volume adjustment; no
dynamics are applied, so the result of using this command is that the loudest parts of each
selected clip are going to match one another at the target level. This command is also available
in the Fairlight page.
To normalize one or more selected audio clips:
1 Right-click one of the selected clips and choose Normalize Audio Levels. The
Normalize Audio Level dialog appears.
The Normalize Dialog in the Edit page
2 Choose the Normalization Mode you want to use. You can choose among a variety of
standardized loudness measurement algorithms, or Sample Peak, or True Peak.
3 Choose the reference level that you want to set the peak volume of the selected clips
to match.
