2.3 Basic Loudness Enhancement Procedure
For basic loudness enhancement, the procedure is to get the programme up to maximum
normalised level at the input (0dBr) in order to fully benefit from the Inflator process, apply
the Inflator processing to get the desired effect, and then adjust the output level to
maintain desired maximum modulation.
Start with the
CLIP 0dBr function selected to limit the range of the Inflator to normal
digital maximum.
Using the
INPUT level control and input meter, set the level such that the red 0 db over
indicator flashes occasionally to indicate the presence of max peak sample values.
Set the
OUTPUT level control to maximum initially, so that the input and output meters
have similar readings when the music is played.
Set the
CURVE control initially to its mid position (default) and deselect the BAND SPLIT
button.
Start with the
EFFECT level control at 100% to obtain the maximum increase in perceived
volume without extra peak output level.
The object of the exercise is to get the input level as high as possible without excessive
distortion or deterioration in the sound. The type of programme material and taste will
determine the extent of the enhancement that can be achieved. If it is found that the
programme material is not significantly degraded at normal peak input levels, further gain
in loudness may be achieved by de-selecting the
CLIP 0dBr button and pushing the input
level into the Inflator overload region.
Note:
Output overloads are entirely avoided
only when the Effect level control is set to
maximum position (100%).
In general the best results are most likely to be obtained by operating the Inflator
EFFECT
level at maximum, and adjusting the
INPUT level and CURVE control to produce the best
sonic compromise.
Further user modifications to the Inflator process can be invoked to gain either greater
loudness or different characteristics in sonic detail, as described below.
