<title>Monitoring</title>
<para>
While monitoring is a broad term, here we use it to refer to the
signal a track delivers to its channel for further processing.
There are two available monitoring states.
These are
'input' (the signal being delivered to a track for potential recording), and
'off-disk' (material you have already recorded, or silence in the absence of a region).

<title>Hardware Monitoring</title>
<para>
Some multichannel audio interfaces have the ability to route an input signal
directly to an output with very low or no latency. This is useful if your computer hardware
is connected to the tape sends and returns of a mixing console.
Whenever monitoring is set to input on a track, the track's input port is connected to its
output in hardware (as would happen on a multitrack tape recorder).
Hardware monitoring provides the best quality assurance for an engineer, as the signal path
is exactly the same for input and off-disk monitoring.
Level differences can be heard immediately, as can other gremlins that may ruin your recording.
The hardware monitoring setting is only useful for interfaces supporting this feature.

<title>Software Monitoring</title>
<para>
Software monitoring uses software to perform input monitoring.
When set to monitor input, a tracks input signal is passed to its channel
as if it were coming from disk, allowing plugins to be heard while recording.
This introduces an inevitable processing delay, or latency, to the input signal.
The size of the delay depends on the current JACK configuration, which should
be set to as short as possible while recording.

<title>Tape Machine Mode</title>
<para>
Nearly all traditional tape recorders use the same monitoring model.
Normally only tracks that are record-enabled will monitor input with the
transport stopped.
Tape machine mode emulates this behaviour.
Some simpler machines (like a famous product by Alesis) switch all tracks to
input on stop when auto-input is enabled, regardless of record-enable state.
Disabling Tape Machine Mode switches to a behaviour that mimics this type of recorder.
Be warned that if you disable Tape Machine Mode, many tracks sharing the same input
(in software monitoring mode) will sum that input through the master buss
(potentially including several plugins) whenever the transport is stopped.
Since setting up a sound usually involves listening to the input with the transport
stopped, you might not be hearing the sound you are about to record!
Disabling this mode can also lead to surprising acoustic feedback.

When a track is record-enabled, it is set to monitor input

when play is engaged. When Ardour is actually recording, the track will be set to
monitor input again.

Once you have recorded material onto a track, the simplest way to punch in
(or drop in as it is known elsewhere) is to roll the transport and press the

Pressing it again disengages record.
