How to make a Shiny App beep / play a sound after a reactive event?

The beep.wav file should be in the /www folder, located in the same directory as the shiny app for the audio Tag to work, see following post.

This works :

library(shiny)

ui <- fluidPage(
    tags$head(tags$script(src = "message-handler.js")),
    actionButton("dobeep", "Play sound")
)

server <- function(input, output, session) {
    observeEvent(input$dobeep, {
        insertUI(selector = "#dobeep",
                 where = "afterEnd",
                 # beep.wav should be in /www of the shiny app
                 ui = tags$audio(src = "beep.wav", type = "audio/wav", autoplay = T, controls = NA, style="display:none;")
        )
    })
}

shinyApp(ui, server)

How do I make JavaScript beep?

It's not possible to do directly in JavaScript. You'll need to embed a short WAV file in the HTML, and then play that via code.

An Example:

<script>
function PlaySound(soundObj) {
  var sound = document.getElementById(soundObj);
  sound.Play();
}
</script>

<embed src="success.wav" autostart="false" width="0" height="0" id="sound1"
enablejavascript="true">

You would then call it from JavaScript code as such:

PlaySound("sound1");

This should do exactly what you want - you'll just need to find/create the beep sound yourself, which should be trivial.

Python: Making a beep noise

On Windows, if you want to just make the computer make a beep sound:

import winsound
frequency = 2500  # Set Frequency To 2500 Hertz
duration = 1000  # Set Duration To 1000 ms == 1 second
winsound.Beep(frequency, duration)

The winsound.Beep() can be used wherever you want the beep to occur.
