Quality
Select either Maximum or Low (Faster) from the
Quality pop-up menu. Maximum is the slowest
processing algorithm, but provides the highest
quality results. Low (Faster) produces relatively
good results and is much faster than the Maxi-
mum
setting.
Formant
For audio material with clear formants, enable
Formant to preserve the formant shape of audio
when applying TCE processing.
Editing in Warp View
In Warp view, you can manually “time warp”
(TCE) audio to correct or adjust the timing of a
performance, or create special effects. In Warp
view, you can add, move, and delete Warp
markers. Warp markers are used to fix a specific
point in the audio (typically a detected transient
event) to a specific point in the Timeline. In this
way, you can apply detailed and nuanced
“warping” (TCE) of audio events.
To display Warp view:
1 Click the Elastic Audio-enabled track’s Track
View selector.
2 Select Warp from the Track View pop-up menu.
Elastic Audio Markers in Warp
View
Three types of markers are visible in Warp view:
Event markers, Warp markers, and Tempo
Event–generated Warp markers. Use Event
markers and Warp markers as control points for
applying Elastic Audio processing.
Audio with a fundamental pitch has an
overtone series, or set of higher harmonics.
The strength of these higher harmonics cre-
ates a formant shape, which is apparent if
viewed using a spectrum analyzer. The over-
tone series, or harmonics, have the same
spacing related to the pitch and have the
same general shape regardless of what the
fundamental pitch is. It is this formant
shape that gives the audio its overall char-
acteristic sound or timbre. When pitch
shifting audio, the formant shape is shifted
with the rest of the material, which can re-
sult in an unnatural sound. Keeping this
shape constant is critical to formant correct
pitch shifting and achieving a natural
sounding result.
Warp view is only available for Elastic
Audio-enabled tracks.
