# Slide Audio, Presentation Audio, and Sound Effects

> How to set up Slide audio and Presentation audio on AhaSlides, how the two interact, and how to enable or disable sound effects on the presenter screen and participant devices.

You can play audio on a single slide (Slide audio) or across the whole presentation (Presentation audio), and you can turn sound effects on or off for greater control over the experience.

<Note>
  Slide audio and Presentation audio are available only on paid plans. Sound effects are available on all plans.
</Note>

## How Audio Works

On AhaSlides, you can set audio to play on each slide as you present (Slide audio) or throughout the entire presentation (Presentation audio).

Slide audio can play on participants' devices, but Presentation audio cannot. Presentation audio autoplays only on the presenter's device for the duration of the presentation.

While you present, the audio controls appear in the top-left corner of the slide whenever audio is playing. Hover over the **Musical note icon** to:

* Turn off the audio by clicking the icon.
* Open the control bar to pause, play, or adjust the volume.

When both Presentation audio and Slide audio are set up, Slide audio takes priority on the slides that have it. Any slide without Slide audio reverts to playing the Presentation audio.

<Note>
  The quiz Lobby screen always has its own music. You can turn it off only by clicking the **Musical note** icon. You cannot set up audio on the Spinner Wheel, YouTube slide, or QR Code slide.
</Note>

## How to Set Up Slide Audio

<Steps>
  <Step title="Open the Audio section">
    Select the slide you want to play audio on, then click the **Audio** section on the right side of the editor.
  </Step>

  <Step title="Choose or upload a track">
    Under the **Slide** tab, either select a song from the AhaSlides audio library in the dropdown, or click **Upload** to add your own audio. Uploads must be mp3 format with a maximum size of 15 MB.
  </Step>

  <Step title="Configure playback settings">
    Once you select or upload a track, you see checkboxes for the audio settings:

    * **Autoplay**: the audio plays immediately when you arrive at the slide.
    * **On repeat**: the audio plays again automatically when it finishes.
    * **Playable on audience's devices**: the audio plays through the audience's devices as well as the presenter's. When checked, a **Show media controls** checkbox appears, which lets the audience play, pause, and adjust the volume on their own devices.
  </Step>
</Steps>

<Note>
  Some devices prevent audio from playing automatically. On those devices, the participant sees a prompt to press the play button.
</Note>

## How to Set Up Presentation Audio

<Steps>
  <Step title="Open the Audio section">
    Select any slide in your presentation, then click the **Audio** section on the right side of the editor.
  </Step>

  <Step title="Choose a track">
    Under the **Presentation** tab, select a song from the dropdown.
  </Step>
</Steps>

<Note>
  You cannot upload your own audio file as Presentation audio yet. Presentation audio does not play on slides that already have Slide audio.
</Note>

## How Sound Effects Work

Sound effects can play on both the presenter screen and participants' devices, depending on the interaction.

On the presenter screen, sound effects help guide the flow of the presentation:

* **Micro-interactions**: button clicks and answer reveals
* **Transitions**: moving to the next slide, a QR code appearing, submissions closing
* **High-impact moments**: countdowns, drumrolls, leaderboard reveals
* **Atmosphere**: background music as participants join, from start to finish

On participants' devices, sound effects provide feedback during interactions:

* When submitting answers on quiz slides
* Result notifications, including correct or incorrect answers, time's up, and answer streaks

## How to Enable or Disable Sound Effects

<Steps>
  <Step title="Open the Audio section">
    Select any slide in your presentation, then click the **Audio** section on the right side of the editor.
  </Step>

  <Step title="Toggle sound effects">
    Under the **Presentation** tab, use the toggles under **Sound effects** next to **On the presenting screen** or **On participants' devices** to enable or disable them.
  </Step>
</Steps>
