12 <strong>DSP CPU Utilization</strong> sets how many cpu processors can be
13 used to do signal processing. It can be set to use one up to all
25 <strong>Limit undo history</strong> sets how many commands can be
26 undone using <kbd class="mod1">Z</kbd> or
27 <kbd class="menu">Edit > Undo</kbd>.
33 <strong>Save undo history</strong> sets how many commands are saved so
34 they are available to be undone after reopening the session.
40 <strong>Verify removal of last capture</strong> when enabled prompts to
41 verify removal the last recording capture when
42 <kbd class="menu">Edit > Remove Last Capture</kbd> is executed.
48 <strong>Make periodic backups of the session file</strong> will create
49 a backup session file after changes to the timeline. The backup file is
50 the session name followed by <em>.ardour.bak</em>. The backup can be
51 used to recover from crashes when the session had not been explicitly
60 <dfn>Session Management</dfn>
65 <strong>Always copy imported files</strong> selects, and then disables
66 changes to, the <em>Copy files to session</em> option in the
67 <a href="@@import-dialog">
68 Add Existing Media</a> dialog.
74 <strong>Default folder for new sessions:</strong> defaults the folder
75 where Ardour will create new session folders. This is used in the
76 <em>Session Setup</em> dialog displayed by
77 <kbd class="menu">Session > New</kbd>.
83 <strong>Maximum number of recent sessions:</strong> determines how many
84 of the last opened sessions shows in the
85 <em>Recent Sessions</em> dialog displayed by
86 <kbd class="menu">Session > Recent</kbd>.
99 <strong>Click audio file:</strong> sets a user defined sound to be
100 played when Ardour's metronome is enabled in the
101 <a href="@@transport-bar">
107 <strong>Click emphasis audio file:</strong> sets an optional different
108 metronome sound to be played on the downbeat.
113 <strong>Click gain level:</strong> allows the metronome's click sounds
114 to be boosted or attenuated.
122 <dfn>Automation</dfn>
127 <strong>Thinning factor</strong> ranges from 0 to 1000 with larger
128 values sending fewer automation changes. Thinning is like lossy
129 audio compression, removing data that is less likely to be noticed,
130 although the more you remove the more likely the loss will be noticed.
131 The advantage to thinning is reduced CPU usage.
136 <strong>Automation sampling interval</strong> ranges from 1 to
137 1000 ms. Determines how frequently the automation input is
138 sampled. The shorter the interval the higher the accuracy but also
139 the higher the CPU requirements.
