🟧 Play sound

The Play sound block triggers a one-off sound effect, noise, or voiceover in your application.

Two options let you go further: making the rest of the flow wait until the sound finishes, and tagging the sound so it can be stopped later with the Stop sound block.

📥 Entries

• sound: Audio file to play (sound effect, sound effects or voiceover).
• tag (Text): Custom label to identify this sound and target it with the Stop sound block.
• wait (Boolean): If enabled (True), the stream waits for reading to finish before continuing. Disabled (False) by default.

📤 Outings

• out (Stream): Allows you to plug in the rest of the flow. If wait is enabled, this output will not activate until the sound has finished playing.

💡 Example of use

Scenario: Sound validation of a user action

1. The user clicks a "Submit" button on a form.
2. The stream arrives at the Play sound block to confirm sending.
3. The block is configured with:

• sound: A "validation.mp3" file (confirmation sound).
• wait: Enabled (True) to prevent the success message from being displayed too early.
• tag: "confirmation_send" (in case the user cancels the action).

1. The validation sound plays, and the flow waits for it to complete before moving to the next step.
2. A message “Your request has been sent!” appears on the screen.

⚙️ Technical Details

• Stream behavior: If wait is disabled, the block starts reading in the background and immediately goes to out.
• Tag management: The same tag can be reused to stop a sound in progress via the Stop sound block, even if it was launched by a different instance of Play sound.
• Supported formats: Audio files must be in MP3, WAV or OGG format for optimal compatibility.
