Audio assets ​

Use audio assets in Arcweave to add music, sound effects, or narration to your interactive project. When you attach an audio asset to an element, it will automatically play when that element is rendered in Play Mode.

Supported file types ​

Arcweave supports the following audio formats:

  • .mp3
  • .ogg
  • .wav
  • .webm

You can upload these file types as assets and attach them to elements in your project.

Preview audio assets ​

You can preview audio directly from the Assets section and set the asset's default playback settings.

To preview an audio asset:

  1. Locate it in the Assets section.
  2. Click the asset to open its preview.
  3. Play the asset, seek through it, and adjust its volume slider. Use the speaker icon to mute or unmute it.
  4. Optionally, set the asset's Fade in and Fade out durations in milliseconds.

The volume and fade durations are the asset's defaults. Every audio reference to the asset uses them unless it overrides them, helping you balance audio across your project.

ℹ️ Note: Play Mode has a volume slider to control the overall playback volume.

Attach audio assets ​

To get the audio assets to play in your story, you need to attach them to elements. See elements for instructions.

Audio reference settings ​

Each audio asset attached to an element is an audio reference. Click an attached audio asset on the element to open its Audio reference dialog, which has its own preview and volume slider, followed by its Play mode settings.

Changes to a reference affect only that element's attachment, not the asset or its other references.

Audio behavior ​

Set the reference's playback behavior to one of the following:

  • Play clip once: Plays the audio a single time when the element is reached in the flow and rendered.
  • Loop clip: Continuously loops the audio until it is stopped.
  • Stop playing all instances of this clip: Stops playback of the specified audio asset wherever it is currently playing.

Delay ​

To fine-tune playback timing, add a Delay in milliseconds before the audio starts. This allows you to synchronize sound with other actions or create dramatic timing effects. Each reference has its own delay, which defaults to 0.

Fades ​

  • Fade in: Milliseconds for the audio to fade in from silence when it starts playing.
  • Fade out: Milliseconds for the audio to fade out when it stops. A Play clip once reference also fades out at the end of the clip.

With Stop playing all instances of this clip, the reference's Fade out sets how the stopped clips fade out; Delay, Fade in, and Auto-stop on element exit don't apply.

Auto-stop on element exit ​

Select Auto-stop on element exit to stop the audio, using its fade out, when Play Mode moves to another element. Otherwise, the audio keeps playing until it ends or is stopped by another reference.

Override asset defaults ​

A reference uses the asset's volume, Fade in, and Fade out unless you change them in the Audio reference dialog. A changed fade field is highlighted. To use the asset's value again, click Reset to asset default (the circular arrow icon) next to the volume slider or fade field.
