How to play voice bleeps in a Ren'Py game

This tutorial shows how to play a looping voice bleep while Ren’Py reveals dialogue text.

Add the bleep sound

Add a bleep audio file in your game directory. For example:

game/audio/bleep.ogg

Create a dedicated audio channel

Register a custom channel in your .rpy script:

# game/script.rpy
init python:
    BLEEP_CHANNEL = "bleep"
    renpy.music.register_channel(BLEEP_CHANNEL, mixer="voice", loop=True)

Setting the voice mixer means the bleep follows the game’s voice-volume setting.

Enabling loop makes the sound repeat until the channel is stopped.

Using a separate channel is useful because the bleep will not interfere with background music, sound effects, or actual voice clips.

Create the dialogue callback

Add a callback function:

def voice_callback(event, **kwargs):
    if event == "show_done":
        renpy.music.play("audio/bleep.ogg", channel=BLEEP_CHANNEL)
    elif event in ("slow_done", "end"):
        renpy.music.stop(channel=BLEEP_CHANNEL, fadeout=0.2)

The callback receives events from the dialogue system:

• show_done starts the looping bleep.
• slow_done stops it after the text has finished appearing.
• end stops the bleep if the dialogue interaction ends (skipped/interrupted).

The fadeout gives the sound a smooth fade instead of cutting it off abruptly.

Attach the callback to a character

Define a character using the callback:

define e = Character("Eileen", callback=voice_callback)

Now your bleep should play:

label start:
    e "This dialogue uses a looping bleep while the text appears."
    e "The bleep stops when the line is complete."
    return

Play a sound when dialogue is dismissed

Optionally, you can play a sound when the dialogue is dismissed:

def dismiss_callback():
    renpy.sound.play("audio/click.ogg")
    return True

config.say_allow_dismiss = dismiss_callback

Script

Here’s the full script:

# game/script.rpy
init python:
    BLEEP_CHANNEL = "bleep"
    renpy.music.register_channel(BLEEP_CHANNEL, mixer="voice", loop=True)

    def voice_callback(event, **kwargs):
        if event == "show_done":
            renpy.music.play("audio/bleep.ogg", channel=BLEEP_CHANNEL)
        elif event in ("slow_done", "end"):
            renpy.music.stop(channel=BLEEP_CHANNEL, fadeout=0.2)

    def dismiss_callback():
        renpy.sound.play("audio/click.ogg")
        return True

    config.say_allow_dismiss = dismiss_callback

define e = Character("Eileen", callback=voice_callback)
