The Latency Compensation Info

The Latency Compensation Info
Latency Compensation Info

This section show information about the latency compensation Ardour sets to align all signals in time whatever their route (and processing applied).

The only button Disable PDC allows to enable/disable the Plugin Delay Compensation. Enabling it will make all signal perfectly aligned, while disabling it will reduce the delay, at the expense of slightly misaligned signals for tracks that have plugins introducing latency.

The two infos are:

  • the worst route latency
  • the I/O latency, i.e. the worst latency pre-roll

The Playhead Options

The playhead options
The playhead options

Those 2 buttons control the behaviour of the playhead:

  • Follow Range is a toggle that can be used to control whether or not making a range selection will move the playhead to the start of the range.
  • Auto Return is a toggle switch too. When active, pressing the Stop button returns the playhead to its previous position, and when inactive, pressing Stop keeps the playhead at its current location. Activating Auto Return can be useful for hearing the same piece of audio before and after tweaking it, without having to set a loop range on it.

The Status indicators

The Status buttons
The Status buttons

The Status buttons show the current session state:

SoloBlinks when one or more tracks are being soloed, see Muting and Soloing. Clicking this button disables any active explicit and implicit solo on all tracks and busses. Clicking this button deactivates the solo on every track/bus.
AuditionBlinks when some audio is auditioned, e.g. by using the import dialog, or using the Audition context menu in the Regions List. Clicking this button stops the auditioning.
FeedbackBlinks when Ardour detects a feedback loop, which happens when the output of an audio signal chain is plugged back to its input. This is probably not wanted and can be dangerous for the hardware and the listener.

The Monitor Section Info

Monitor Section Info
Monitor Section Info

This section is only useful and active if the session has a Monitor section. The three buttons are exactly linked to their counterparts in the Monitor slice of the mixer, but as they sit in the toolbar, remain visible even in Editor mode.

The three buttons are:

  • Mono: sums all of the paths to a single mono signal and applies it to all Monitor Section outputs.
  • Dim All: Reduces overall monitor level by the amount set with the Dim level control.
  • Mute All: Mutes all monitoring.

The Master Level Meter

The Master Level Meter
The Master Level Meter

The global meter shows the levels of the master's output. Its the same meter that sits in the Master's Mixer strip, and also shows a peak indicator, that turns red when any level exceeds 0dB. It can be reset by a Left click.

Script/Shortcut buttons

The Script buttons
The Script/shortcuts buttons

The buttons in between the Mode Selector and the Master Level Meter are script or shortcuts buttons, which are user-definable buttons to attach any session lua-script to, or any action shortcut (e.g. for tasks that are used often and buried deep inside nested menus).

The number of buttons (precisely, the number of columns of two buttons) can be set in the Preferences.

Left-clicking an affected button launches the script or shortcut, while right-clicking or clicking an unaffected button allows change the script/shortcut the button should execute.

The Mode Selector

The Mode Selector
The Mode Selector

The Mode Selector allows switching between the Editor, Mixer or Recording windows. If a window is detached, the corresponding button is lit. Clicking the button switches the detached window visibility.
