9.7. Prerecord Time
This setting buffers a small amount of audio so that when the record button is pressed,
the recording will begin from that number of seconds earlier. This is useful for ensuring
that a recording begins before a cue that is being waited for.
9.8. Clear Recording Directory
Resets the location where the recorded files are saved to the root of your player’s drive.
9.9. Trigger
When you record a source you often are only interested in the sound and not the silence
in between. The recording trigger provides you with a tool to automatically distinguish
between sound and silence and record the sound only. Unfortunately it is not very easy
to make this distinction between silence and sound because you hardly ever encounter
real silence. There always are background noises. What is considered as background
noise depends on the situation. For example during a lecture the very low noise of
rustling paper might be considered as background noise. During a rock concert the
murmur of the audience might be concidered background noise which is much louder
compared to rustling paper. Also the duration of the signal matters. When you record
speech you want to record every syllable. When you record live music you may not be
interested in that chord the guitarist strokes for two minutes before the show to verify
his amp is turned on. The trigger features numerous parameters to adapt its behaviour
to the desired situation.
Trigger
This parameter specifies the trigger mode. When set to O

the recording must
be started manually and apart from the Prerecord time no other parameter has
any effect. O
NCE
will have the trigger start one recording only; after the recording
has finished the input signal will not start another recording. R
EPEAT
will have
the trigger start multiple recordings.

Prerecord Time
This specifies the time that is included into the recording before the
trigger event occurs. This is very useful if you record a signal that fades in. Usu-
ally you want to set the prerecord time ¿= start duration. That ensures that you
record the entire sound. Strictly speaking the prerecord time is not a special pa-
rameter of the trigger. It is available during normal recordings too.
Start Above
The start threshold defines the minimal volume a sound must have to
start the recording. It is displayed numerically in the line ”Start Above”. Note that
the unit of the threshold depends on the settings of the peak meter. (i.e. When the
peak meter displays db you can adjust the level in db and when the peak meter
