9. Turn the Value encoder clockwise or counter-clockwise to change the letter.
The StudioLive allows you to customize the name with uppercase and
lowercase letters and a selection of numerals and punctuation marks. Press
the Tap button to quickly insert a space.
10. Once you are satisfied with your changes, press the Store button, which will
illuminate while the effects preset is written to the StudioLive’s internal
memory. Once the preset is saved, the Store button will return to its unlit
status.
5.1.2 Reverb and its Parameters
Reverberation — or reverb, as it is more commonly known—is perhaps the most
widely used effect. Natural reverb is created by sound waves reflecting off of a surface
or many surfaces. For example, when you walk across the wooden stage in a large
hall, thousands of reflections are generated almost instantaneously as the sound
waves bounce off the floor, walls, and ceilings. These are known as early reflections,
and their pattern provides psycho-acoustic indications as to the nature of the space
that you are in, even if you can’t see it. As each reflection is then reflected off of more
surfaces, the complexity of the sound increases, while the reverb slowly decays.
The reason for the widespread use of reverb in audio recording is fairly self-evident:
human beings don’t live in a vacuum. Because our brains receive cues about the
nature of the space around us based partially on audio reflections, a sense of space
makes an audio recording sound more natural and, therefore, more pleasing.
The following parameters are available for the nine reverb types the StudioLive offers:
Decay. Decay is the time (in seconds) required for the reflections (reverberation)
to die away. In most modern music production, reverb decay times of between
one and three seconds are prevalent. A reverb setting with strong early reflections
and a quick decay are a great way to create a stereo effect from a mono source.
Predelay. Predelay is the time (in milliseconds) between the end of the initial
sound and the moment when the first reflections become audible. Imagine you’re
back on that stage in a large music hall. This time you stand on the very edge of
the stage and shout “Hello world!” toward the center of the hall. There will be a
brief pause before you hear the first noticeable reflections of your voice, because
the sound waves can travel much further before encountering a surface and
bouncing back. (There are closer surfaces, of course—notably the floor and the
ceiling just in front of the stage—but only a small part of the direct sound will go
there, so those reflections will be much less noticeable.) Adjusting the predelay
parameter on a reverb allows you to change the apparent size of the room without
having to change the overall decay time. This will give your mix a little more
transparency by leaving some space between the original sound and its reverb.
Note: Predelay control is not available on every reverb type.
Early Reflections. Early Reflections are those that reach the listener a
few milliseconds after the direct signal arrives. The human brain uses
them to identify the size of the room it is in. If you are trying to simulate
a specific type of room, this control will be extremely important. This
control allows you to set the level (in decibels) of the early reflections.
The louder the early reflections, the smaller the room will seem.
Note: Early Reflections control is not available on every reverb type.
