Monitoring - + + 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). +
Hardware Monitoring - + + 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. +
- +
Software Monitoring - + + 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. +

External Monitoring - + + External Monitoring will silence the output of a track whenever the track is set + to monitor input. It is useful if you are listening to the input signal + using a path outside your computer (eg a mixing console). + +
+ +
+ Tape Machine Mode + + 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. + Tape Machine Mode is off by default. +
Auto-Input - + + When a track is record-enabled, it is set to monitor input + regardless of the transport state. Auto input switches to off-disk monitoring + when play is engaged. When Ardour is actually recording, the track will be set to + monitor input again. + Auto-Input is useful for performing punch-ins. Disable auto-input when performing + 'dry runs' of an overdub to allow a performer to hear themselves while the transport is rolling. +

Punch Recording + + 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 + master record button at the desired in point. Assuming the desired track is + record enabled, its monitoring state will be switched and recording will begin. + Pressing it again disengages record. + If repeatable punch-ins are required, you may use auto punch. + +
