This window exposes the different audio options to be used by Ardour for the
|
|
current work session, for hardware and software and is made of:
|
|
</p>
|
|
|
|
<table class="dl">
|
|
<tr><th>Audio System</th>
|
|
<td>
|
|
Depending on the operating system, Ardour can possibly use different audio
|
|
systems, e.g. on Linux, both <abbr title="Advanced Linux Sound Architecture">
|
|
ALSA</abbr>, PulseAudio, and <abbr title="JACK Audio Connection Kit">JACK</abbr>
|
|
are available. On Mac OS X this will typically be
|
|
<kbd class="menu">CoreAudio</kbd>. Advanced users on all platforms may also
|
|
use <kbd class="menu">NetJack</kbd> which provides network audio I/O.
|
|
</td></tr>
|
|
<tr><th>Input Device</th>
|
|
<td>
|
|
The selector should show all available interfaces provided by the
|
|
audio system above and which are capable of capturing audio.
|
|
</td></tr>
|
|
<tr><th>Output Device</th>
|
|
<td>
|
|
The selector should show all available interfaces provided by the
|
|
audio system above and which are capable of playing audio.
|
|
</td></tr>
|
|
<tr><th>Sample Rate</th>
|
|
<td>
|
|
The selector will allow to select from any sample rate supported by the device
|
|
selected above it.
|
|
</td></tr>
|
|
<tr><th>Buffer Size</th>
|
|
<td>
|
|
The size of the buffer used by the audio interface can be adjusted
|
|
to allow for either lower latency, or lower CPU usage and higher
|
|
latency.
|
|
</td></tr>
|
|
<tr><th>Periods</th>
|
|
<td>
|
|
Number of frames between each hardware interrupt (analog-digital
|
|
or digital-analog conversion).
|
|
</td></tr>
|
|
<tr><th>Hardware Monitoring</th>
|
|
<td>
|
|
This section allows choosing whether Ardour or auidio hardware should be
|
|
handling recording monitoring.
|
|
</td></tr>
|
|
<tr><th>Advanced Settings</th>
|
|
<td>
|
|
This section contains several lower-level settings listed below.
|
|
</td></tr>
|
|
<tr><th>MIDI System</th>
|
|
<td>
|
|
This allows choosing a MIDI driver. On macOS, this will be
|
|
<kbd class="menu">CoreMIDI</kbd>. On Linux, the choice will be between
|
|
ALSA sequencer and ALSA raw devices. Choosing "None" will disable the
|
|
connection to the external MIDI backend and prevent Ardour from being
|
|
exposed to external MIDI ports while allowing to route MIDI events inside
|
|
the program.
|
|

|
|
<tr><th>Setup & Calibration</th>
|
|
<td>
|
|
This button runs a semi-automated guided process to obtain precise
|
|
hardware latency measurements for available MIDI ports.
|
|
</td></tr>
|
|
<tr><th>Hardware Input/Output Latency</th>
|
|
<td>
|
|
Specify the hardware delay in samples for precise latency compensation.
