Audio Analysis
Global Analysis
134
Resolution
The length of audio to be measured and averaged. If this value is
lowered, short passages of loud/weak audio are detected. When
it is raised, the sound must be loud/weak for a longer period to
result in a hot point.
Threshold (for the average)
Ensures that the average value is calculated correctly for
recordings with pauses. The value that you set here determines a
threshold below which any found audio is considered to be
silence, and is therefore excluded from average value calculations.
Maximum number of loudness points to report
Restricts the number of reported hot points. The highest points are
reported. For example,
setting this to “1” reports only the loudest
section or one of the sections with the same highest value.
Minimum time between 2 points
Controls the distance between points, so they do not appear too
close to
each other. For example, setting this to “1 s” ensures that
there is always at least one second between reported points.
Global Analysis - Pitch Tab
This tab is for finding the average pitch of an audio section.
In the Audio Files workspace, select Analysis > Global Analysis, and
select the Pitch tab.
You can use this tab to gather information for pitch shifting, for example,
to get one sound in tune with another. The display shows the pitch for
each channel, both in Hertz (Hz) and as semitones and cents
(hundredths of a semitone). Since the display shows an overall value for
the entire analyzed section, the hot point controls in the lower section of
the dialog are not used on this tab.
Usage guidelines for the Pitch tab:
• The result is an average value for the whole selection.
• The method only works on monophonic material, not on chords or
harmonies.
• The algorithm assumes that the analyzed section has a reasonably
stable pitch.
