Elastic Properties window (see “Event Sensitivity
Property” on page 990). Filtering out any false
transients can result in higher quality Elastic Audio
processing.
Conversely, for material with few clear transients,
Elastic Audio analysis may not accurately detect
audio events, and those detected may be detected
with a low level of confidence. You can relocate or
add Event markers where necessary in Analysis
view (see “Editing in Analysis View” on
page 986).
For example, a slow synth pad may not have clear
transients and detected Event markers may be in-
correctly located or may have not been detected at
all. In Analysis view, you can relocate, remove,
and add Event markers as necessary (such as where
the chord changes). Accurately locating Event
markers yields better results when applying Elastic
Audio processing.
Real-Time and Rendered
Elastic Audio Processing
Real-Time Elastic Audio processing means that
any changes to Elastic Audio processing—whether
it be a tempo change or a manual TCE warp, or
pitch shifting—take effect immediately. However,
Real-Time Elastic Audio processing can be very
demanding on your system’s resources. Conse-
quently, you may want to use Rendered Elastic
Audio processing in some cases. With Rendered
Elastic Audio processing, when you make a
change to Elastic Audio processing, any affected
audio clips temporarily go offline, a new “ren-
dered” audio file is generated, and any affected au-
dio clips come back online.
To set an Elastic Audio track to Real-Time or
Rendered:
1 Click the track’s Elastic Audio Plug-In selector.
2 From the pop-up menu, select an Elastic Audio
plug-in.
3 From the pop-up menu, select one of the
following:
•
Real-Time Processing
•
Rendered Processing
When processing non-rhythmic audio (such
as legato strings) with the Polyphonic plug-
in, reducing the number of Event markers of-
ten yields better sounding results. You can ei-
ther manually remove Event markers in Anal-
ysis view (see “Editing in Analysis View” on
page 986) or lower the Event Sensitivity set-
ting in the Elastic Properties window for the
clip you want to process (see “Elastic Prop-
erties Window” on page 988).
In rendered mode, any change you make is
rendered using the original source audio to
avoid generational loss from multiple subse-
quent edits.
Select Real-Time processing for tick-based
Elastic Audio processing (such as tempo
changes). Rendered audio processing can be
useful for sample-based Elastic Audio
processing or if you need to save system
resources.
