Global Analysis – Pitch Tab

On this tab, you can make settings that help you find the average pitch of an audio section.

• In the Global Analysis dialog, select the Pitch tab.

Settings on this tab allow you to gather information for pitch shifting, for example, to get one sound in tune with another. The display shows the pitch for each channel, in Hertz (Hz) and as semitones and cents (hundredths of a semitone). Because 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.

• The material must be relatively well isolated from other sounds.

• It is preferable to analyze the sustain portion of a sound rather than the attack. The pitch is usually not stable during the attack.

• Some synthetic sounds may have a weak fundamental (first harmonic) which can irritate the algorithm.
