<p>The status bar is an informative bar at the top of the window, showing:</p>
|

|
|
<dl>
|
|
<dt>File:</dt><dd>the file format used in the session, including when recording</dd>
|
|
<dt>TC:</dt><dd>is the timecode, i.e. the number of frames per second used by the session (for videos)</dd>
|
|
<dt>Audio:</dt><dd>gives the sample rate used in the session, and the latency computed from the buffer size</dd>
|
|
<dt>Buffers:</dt><dd>decribe how much data is buffered, see below</dd>
|
|
<dt>DSP:</dt><dd>for Digital Sound Processing, shows how much of the CPU is used by Ardour and its plugins</dd>
|
|
<dt>PkBld:</dt><dd><em>(only shows up while creating peaks)</em> displays the number of peak files left to create</dd>
|
|
<dt>X:</dt><dd>shows the number of xruns since Ardour's launch, see below</dd>
|
|
<dt>Disk:</dt><dd>reports the remaining hard disk space as the time that can be recorded with the current session setting</dd>
|
|
<dt>Wall Clock</dt><dd>showing the system time (especially usefull in full screen mode)</dd>
|
|
<dt>Log button</dt><dd>that indicates if Ardour has encountered any warning or error.</dd>

Right clicking anywhere on the Status Bar allows to choose which of this informations we want displayed, through a checkbox menu.

The buffers are labelled as <kbd class="menu">p</kbd> for playback and <kbd class="menu">c</kbd> for capture. If the
|
|
system is fast enough, these buffers should be 100% full at all times, showing the system has time to precompute
|
|
all the data before delivering it to the audio system. A buffer constantly under 20% is a sign of an underpowered
|
|
computer system or of too much processing.
|
|
</p>
|
|
<p>
|
|
An Xrun (short for buffer over- or under-run) happens when the system has been forced to skip audio frames, e.g. if the latency
|
|
asked is too short for the computing power of the machine. It usually results in clicks, pops and crackles if it happens while recording.

The log button turns yellow when a warning is shown, and red when an error occurs. Clicking the log button gives acces to the log.
