pointing to the right. There are two special values. The value
Off
turns the start
condition off. With this setting you have to start the recording manually and the
trigger only stops the recording according to the stop condition. The setting
-inf
sets the trigger to the absolute minimum. This setting only makes sense when you
record via a digital input as even the noise of the device itself would exceed this
threshold immediately.
for at least.
The start duration defines the minimal duration that a signal must ex-
ceed the start threshold to start the recording. Depending on your situation you
may want to set this setting to 0 (e.g. when copying a song from a commercial
medium) or to quite big values. Because sound is not continuous by nature (think
of percussion) negligible dropouts are tolerated during this start duration.
Stop Below.
When the sound level drops below the stop threshold the recording is
stopped. It is displayed numerically in the line “Stop Below”. Just like the start
threshold the unit of the stop threshold depends on the settings of the peak meter.
There’s also a small triangular marker in the peak meter at the bottom of the
screen. In contrast to the start threshold marker it points to the left. The value
Off
turns the stop condition off. With this setting you have to stop the recording
manually.
for at least.
This time specifies the duration the signal must drop below the stop thresh-
old to stop the recording. By selecting high values you can ensure that, for example,
trailing fade-outs are recorded entirely.
Presplit Gap.
When the signal drops below the stop threshold for the time specified by
the presplit gap a new recording may be started when the signal raises above the
start threshold. Thus the value of the presplit gap should be smaller than the stop
hold time. Otherwise the recording would stop anyway and the presplit gap has
no effect. For most uses I recommend to set this parameter equal to the stop hold
time. Sometimes you may encounter a sound source (e.g. a CD) where the songs
have fade outs and hardly any gaps between the tracks. Here you can set the stop
hold time to long values to ensure that all fade outs are recorded completely. By
specifying a short presplit gap you still can split the recording into separate tracks
whenever the trigger start condition is met.
