DRC - Dynamic Range Compression
|
||
===============================
|
||
|
||
|
||
|
||
Dynamic Range Compression
|
||
-------------------------
|
||
|
||
The dynamic range of an audio track is the difference between the softest and
|
||
loudest sounds.
|
||
|
||
Dynamic range compression reduces the gap between those extremes.
|
||
|
||
On the Audio tab, each track provides an option to set the level of compression
|
||
you wish.
|
||
|
||
- 1.0-2.5 are good values to use.
|
||
|
||
- 0, the default, turns it off completely.
|
||
|
||
- 1.0 uses the compression hints embedded in the AC3 track.
|
||
|
||
Values greater than 1.0 compress the range further by boosting the volume of
|
||
soft sound samples while leaving loud samples as they are. This squeezes down
|
||
the range between the softest and loudest parts, but should make the softer ones
|
||
easier to hear in noisy listening environments. Note, this is not the same as a
|
||
gain or volume boost control.
|
||
|
||
|
||
|
||
Compatibility
|
||
-------------
|
||
|
||
Dynamic range compression only works when the source audio is AC3 and you are
|
||
encoding to another format, like AAC. It has no affect on AC3 pass-through or on
|
||
DTS or MPEG-2 audio.
