Processing : Elastic Audio : Elastic Properties Window : Event Sensitivity Property

Event Sensitivity Property
The Event Sensitivity property in the Elastic Properties window lets you filter Event markers based on the analysis confidence level. The confidence level for any detected transient event is based, in part, on the clarity of the transient. For example, if the file is a drum loop, loud accented hits will be analyzed with a higher degree of confidence than a soft, unaccented hit.
The Event Sensitivity acts like a threshold for showing only the transient events that were detected with a high degree of confidence. In Warp or Analysis track views you will see the number of Event markers decrease or increase as you lower or raise the Event Sensitivity.
Lowering the event sensitivity can help reduce the number of erroneously detected transients. In turn, this can result in better sounding Elastic Audio processing. Pro Tools preserves the detected transients when applying TCE in order to avoid flamming and granulation of the transients. Consequently, false transients are also preserved and the resulting sound quality can be less than desirable. If you are working with audio material that does not have clearly defined transients, you may want to lower the Event Sensitivity in the Elastic Properties, or you may want to even edit the Event markers in Analysis view.
If lowering the Event Sensitivity results in filtering out important Event markers, you can promote those Event markers in Analysis view (see Promoting Event Markers).

For REX files, Pro Tools converts the slices as Events with 100% confidence. Consequently, setting the Event Sensitivity from 99% to 1% does not filter out any events based on slices. However, if you set the Event Sensitivity to 0%, all markers are filtered out regardless.

When you change the Event Sensitivity property, Pro Tools writes temporary filtered Elastic Audio analysis files (.aan) to the session’s Rendered Files folder. Any unused temporary filtered analysis files are purged when you close the session.
