4.3.3 Sample-Aligned Configuration Using Markers
Configuration changes based on the frequency or amplitude table are not exactly
aligned to the sample data and may vary for each change by some samples.
For more accurate and exactly reproducible results, the action table needs to be used
instead. All configuration changes, based on this mechanism become active with the
next sample marker. So a sample marker can be used to select a well-defined position
relative to the sample data at which a configuration change becomes active.
The following table shows the accuracy of configuration changes depending on the
interpolation mode when using the action table:
