4.2.4.3. Recovery
This corresponds to the release time (the time it takes for the compressor to restore the
original audio behavior, after compression), as seen in most other compressors .
The Recovery parameter may be considered the inseparable partner of the Attack. As the
latter controls the time it takes for compression to start when the Threshold is exceeded, the
former tells the Compressor how long it should take to bring the signal back to the original
value after it has fallen back under the Threshold.
As you can see, all these parameters are linked. Attack and Release act like the segments of
an envelope triggered by the Threshold, and whose sustain level is defined by the Ratio. In
this case, the envelope is inverted, which means the sustain level is lower than the original
level.
Since Recovery is a time parameter, it can be faster, or slower (just like Attack). The effect
it has varies, depending on the type of audio you are dealing with (again, just like with the
Attack parameter). It is also tied to the Attack time in use, especially if we are dealing with
complex audio, which may be the case with the Comp DIODE-609. You may wish to check
the
for details on how to use these two parameters combined.
Release times in the Comp DIODE-609 are also expressed in milliseconds. This control only
accepts fixed (predetermined) values. The values accepted are 100 ms, 400 ms, 800 ms,
1500 ms. Besides these, you have two extra positions, labeled "
a1
" and "
a2
", which are
automatic recovery times. In these positions, recovery is self adjusting, and is faster for
transient peaks and slower for persistent higher audio levels, to preserve a more natural
dynamic range and behavior. These auto recovery times just have two different time
constants to suit different program material, like speech vs music.
a1
varies the release
times between 100 ms and 2 seconds, while
a2
varies the release times between 50 ms
and 5 seconds. The best way to check how handy these may be is for you to try them out
(in case you want to use automatic recovery times, of course), to see which one better suits
what you want to achieve.
By default, the Recovery time is positioned at 100 ms.
4.2.4.4. Makeup Gain
Because, by nature, compressors reduce the overall volume level, we need to raise the final
output volume in order to compensate for that reduction. That's what Make-Up Gain is there
for.
Range goes from 0 dB to +20 dB. By default, the control is set to 0 dB (no gain).
