LibreOffice Impress Slide Sounds and Loop Options

LibreOffice Impress provides several audio and playback settings to enhance multimedia presentations, including built-in transition sounds, custom audio integration, and automated presentation looping. Users can assign specific audio cues to slide transitions, configure sounds to repeat continuously, or set the entire slide deck to run on an automatic, endless loop for kiosks and displays.

Slide Transition Sound Options

Transition sounds play automatically when a slide appears on the screen. These settings are managed via the Slide Transition panel in the right-hand sidebar.

Built-in Sound Effects: Impress includes a variety of preset audio clips, such as Applause, Arrow, Beam, Chime, Laser, and Voltage.
Custom Audio Files: By selecting Other sound… from the Sound drop-down list, you can import external audio files (such as .wav formats) from your local drive.
Stop Previous Sound: Choosing this option terminates any audio triggered by a previous slide transition without playing a new sound.
No Sound: The default setting, which ensures the slide transition remains completely silent.

Audio Loop Settings for Transitions

Under the same Slide Transition sidebar panel, Impress includes a specific option for audio continuity:

Loop Until Next Sound: Enabling this checkbox causes the selected transition sound file to repeat continuously in a loop until another slide with an assigned sound effect is reached, or until a slide set to “Stop Previous Sound” appears.

Presentation Loop and Auto-Repeat Settings

To loop the entire presentation continuously rather than just individual sounds, Impress includes presentation playback controls:

Go to the top menu and select Slide Show > Slide Show Settings…
Under the Presentation Mode section, select Loop and repeat after:.
Set the duration for the pause between loops (e.g., 00:00:00 for an immediate restart).
Optionally, check Show logo to display the LibreOffice logo during the pause interval between presentation cycles.
