A wave/mp3 file in shiny?

Hello everyone!

Does anyone here ever tried to use audio files in a shiny app?
I'm not talking about chip music.

Thanks!

The answer at the following link shows how to add audio files:

Basically, you need to add an audio tag and specify the audio file you'll be using. This audio file must be in a www folder within your shiny project.

I have a Shiny module in googleLanguageR that will play audio - I needed it for text-to-speech, but it should work with any audio file:

github.com

ropensci/googleLanguageR/blob/2b4dc881079261120fbbeda6932db13d2de0754a/R/text-to-speech.R#L205-L302


#' Speak in Shiny module (ui)
#'
#' @param id The Shiny id
#'
#' @details
#'
#' Shiny Module for use with \link{gl_talk_shiny}.
#'
#' @export
gl_talk_shinyUI <- function(id){
  ns <- shiny::NS(id)


  shiny::htmlOutput(ns("talk"))


}


#' Speak in Shiny module (server)
#'
#' Call via \code{shiny::callModule(gl_talk_shiny, "your_id")}
#'

Thanks everyone! It was helpful!

Do you know how to make the audio autoplay?

In the linked file, you can see an example - set autoplay attribute to NA

    shiny::tags$audio(autoplay = NA,
                      shiny::tags$source(src = wav_file()))
