\item[Trigger.]
This parameter specifies the trigger mode. When set to \setting{Off}
the recording must be started manually and apart from the Prerecord time no
other parameter has any effect. \setting{Once} will have the trigger start
one recording only; after the recording has finished the input signal will
not start another recording. \setting{Repeat} will have the trigger start
multiple recordings.

\item[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. Usually you want to set the prerecord time greater than or
equal to the start duration. That ensures that you record the entire
sound. Strictly speaking the prerecord time is not a special parameter
of the trigger. It is available during normal recordings too.

sound. Strictly speaking the prerecord time is not a special parameter
of the trigger. It is available during normal recordings too.
\item[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 is set to linear the threshold is displayed as percentage.) In the
peak meter at the bottom of the screen the start threshold is displayed
graphically by a little triangle pointing to the right. There are two special
values. The value \setting{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 \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.

\item[for at least.]
The start duration defines the minimal duration that a signal must exceed 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) neglectable dropouts are tolerated during this start
duration.

\item[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 \setting{Off} turns the stop condition off. With this setting you
have to stop the recording manually.

\item[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 seperate tracks whenever the trigger start
condition is met.

@ -468,7 +468,7 @@ There are several settings associated with the compressor. The first, and most
important, is the \setting{Threshold}. The threshold is the audio input level
at which the compressor begins to act. Any level louder than the threshold
will be compressed to some extent. The maximum amount of compression, or the
quietest level at which the compressor will operate, is -24db. The default of
