• At a setting of −100% (switch −1), all intervals are mirrored.
The Pitch Base parameter is used to transpose the note that the Tracking parameter is
following. As an example: the note which is spoken, if Tracking is set to 0%.
Pitch Correction
The Pitch Correction plug-in enables you to correct the pitch of audio tracks. Improper
intonation is a common problem with vocal tracks, and this can be easily fixed with the
Pitch Correction plug-in. The sonic artefacts of the process are minimal and can barely
be heard, as long as the corrections are moderate. The natural articulation of the per-
formance is preserved. Should large transposition intervals be used, you can achieve a
static pitch, thus creating an interesting effect, known as the “Cher” effect. Any scale
can be defined as a pitch quantization grid. Improperly intonated notes will be correc-
ted to this grid. The keyboard at the center of the Plug-in window is used to define the
scale that will serve as the pitch quantization grid.
Note: Polyphonic Recordings (choirs on one track) and highly percussive signals, with
prominent noisy portions, can’t be corrected to a specific pitch. Despite this, feel free to
try the plug-in on drum tracks!
Function Principle
The Pitch Correction algorithm is designed for corrections of smaller pitch shifting
intervals. The correction works in a similar fashion to an audio tape, with the playback
speed accelerated and slowed down in a way that ensures the singing voice always
matches the correct note pitch. If you force the algorithm to correct larger intervals,
you can create special effects.
