Chapter 21 Editing Audio in the Sample Editor 541
To open the Audio Energizer, do one of the following:
m Choose Factory > Audio Energizer in the Sample Editor (or use the corresponding key
command).
m Click the Audio Energizer tab if another Digital Factory processor is visible.
Factor
Set the amount of average level boost. A value of 0% means no alteration, while higher
values produce an increase in energy. The setting you make here will depend on the
audio material, situation, and personal taste.
 Begin by trying values in the 40 to 100% range.
 Values below 10% will have little effect.
 Values over 100% can lead to undesirable alterations in the sound, depending on the
material.
 Values over 200% are not recommended with normalized files, because they will
have detrimental effects on the sound and its dynamics. They can also greatly
increase the required computation time. On non-normalized audio data, however,
even high values can be effective because the overall level is initially increased to its
maximum, without affecting the dynamic range.
Attack and Decay
These parameters control the steepness of the algorithm’s filter. Try values of 2 to 4
times the default, if the result sounds too digital or raw. This can happen if smaller
elements among the main events in the signal are boosted. As an example, the reverb
portion of a sound can become louder.
