2.5 Deadband 2 OPERATION
2.5 Deadband
The deadband value provides a method to exclude
less significant transient modifications from the
final processing output. For example, if a deadband
of 3dB is set, changes resulting from the TransMod
processing below a total differential gain change
of 3dB are excluded from the process, and the
signal is unaffected under these conditions.
The deadband control can be used to prevent
action from small level changes or insignificant
transients, which may otherwise adversely affect
the programme. In this case, it is best to start with the deadband set to zero and increase
it only if unwanted action becomes evident, particularly during quiet sustained
passages.
The deadband control may also be used to produce dramatic effects by focussing the
TransMod action on only the loudest transients in the programme. In this case, it’s best to
set low thresholds and high ratios to get the maximum action, before progressively
increasing the deadband to exclude smaller events from the effect.
2.6 Threshold
The threshold control causes the process to operate only on programme material above
the set level, ignoring all signals below that value. Unlike all the other TransMod
processing, the threshold is related to absolute input levels, and therefore care must be
taken to set a low enough threshold value to allow action on the required range of
programme.
Careful threshold setting may be used to focus only on the louder events in the
programme. This may be particularly useful when aiming for compression sounds with
negative ratio settings. To generate increased attack with positive ratios, the TransMod
process works most effectively when operating on the majority of the programme range,
i.e. the lower the threshold the greater the possible effect may be.
Note:
Care must be taken with very low threshold settings since programme material starting
