Audio alarm is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

AudioAlarm is a program that asks the user to enter a certain number, representing a number of seconds. After the user enters the number, the program will ask the user to enter the name of an MP3 audio file (without the .mp3 file extension). The program will then display a (usually blank) page. After the time (indicated by the number) is up, a sound (indicated by the MP3 file) will go off. Useful for timers and alarm clocks. The app must be installed in its own folder, preferrably with a name like AudioAlarm. To install a sound on the app, just copy the MP3 to the app folder you set up. Then, when the app asks you for the filename, you just type in the name without an extension.

Batch File

Get user input
%alarm% can have spaces, but cannot have quotation marks ("")
%time% has a working range of -1 to 99999 seconds
input

set /p "time=Input amount of time in seconds to wait: " set /p "alarm=Input name of alarm: "

Check if %time% is an integer with 'set /a'

set /a intcheck=%time% if %intcheck%==0 goto input

cls timeout /t %time% /nobreak >nul start "" "%alarm%.mp3" </lang>

Output:
Input amount of time in seconds to wait: 5
Input name of alarm: alarm name with spaces

Go

As Go does not have any audio support in its standard library, this invokes the SoX utility's 'play' command to play the required .mp3 file. <lang go>package main

import (

   "log"

)

   number := 0
   for number < 1 {
       fmt.Print("Enter number of seconds delay > 0 : ")
       scanner.Scan()
       input := scanner.Text()
       if err := scanner.Err(); err != nil {
           log.Fatal(err)
       }
       number, _ = strconv.Atoi(input)
   }

   filename := ""
   for filename == "" {
       fmt.Print("Enter name of .mp3 file to play (without extension) : ")
       scanner.Scan()
       filename = scanner.Text()
       if err := scanner.Err(); err != nil {
           log.Fatal(err)
       }
   }

   cls := "\033[2J\033[0;0H" // ANSI escape code to clear screen and home cursor
   fmt.Printf("%sAlarm will sound in %d seconds...", cls, number)
   time.Sleep(time.Duration(number) * time.Second)
   fmt.Printf(cls)
   cmd := exec.Command("play", filename+".mp3")

Enter name of MP3 file (without the extension) to sound alarm : alarm

LB can play wav files natively. Here we call the standard Windows Media Player for an MP3. If not already running, this will add an extra delay... It will error if the mp3 file does not exist in the specified path. <lang lb>nomainwin

Features:

  • Pd has built-in WAV file support - mp3 will require an extension
  • Time input by hours, minutes and seconds
  • Start, pause and resume button
  • Sound file selection via file browser dialog, test button and volume control

Python

Python natively supports playing .wav files (via the wave library), but not .mp3. Therefore, this calls to the OS to start the file. This behaves as though the mp3 file were double-clicked and plays the file with the default system player.

Works with: Python version 3.4.1

<lang python>import time import os

seconds = input("Enter a number of seconds: ") sound = input("Enter an mp3 filename: ")

time.sleep(float(seconds)) os.startfile(sound + ".mp3")</lang>

Racket

Racket does not currently have native mp3 support so this example uses system to call an external application. <lang racket>#lang racket (display "Time to wait in seconds: ") (define time (string->number (read-line)))

(display "File Name: ") (define file-name (read-line))

(when (file-exists? (string->path (string-append file-name ".mp3"))) 

 (sleep time)
 (system* "/usr/bin/mpg123" (string-append file-name ".mp3")))</lang>

REXX

using SLEEP

<lang rexx>/*REXX pgm to prompt user for: # (of secs); a name of a MP3 file to play*/

say '──────── Please enter a number of seconds to wait:' parse pull waitTime . 

                        /*add code to verify number is a valid number. */

say '──────── Please enter a name of an MP3 file to play:' parse pull MP3FILE 

                       /*add code to verify answer is a valid filename.*/

call sleep waitTime MP3FILE'.MP3' 

                                      /*stick a fork in it, we're done.*/</lang>

output when using the input of: xxx

using spin

<lang rexx>/*REXX pgm to prompt user for: # (of secs); a name of a MP3 file to play*/

say '──────── Please enter a number of seconds to wait:' parse pull waitTime .

say '──────── Please enter a name of an MP3 file to play:' parse pull MP3FILE

call time 'Reset' /*reset the REXX (elapsed) timer.*/ 

  do  until time('E')  >waitTime      /*wait out the clock (in seconds)*/
  end

MP3FILE'.MP3' 

                                      /*stick a fork in it, we're done.*/</lang>

Ring

<lang ring>

  1. Project : AudioAlarm

load "stdlib.ring" see "Delay in seconds: " give sec see "MP3 to play as alarm: " give mp3 f = mp3 + ".mp3" sleep(sec) system("C:\Ring\wmplayer.exe C:\Ring\calmosoft\" + f) </lang> Output:

Ruby

requires mpg123 to be installed.

<lang ruby>puts "Enter a number of seconds:" seconds = gets.chomp.to_i puts "Enter a MP3 file to be played" mp3filepath = File.dirname(__FILE__) + "/" + gets.chomp + ".mp3" sleep(seconds) pid = fork{ exec 'mpg123','-q', mp3filepath } </lang>

Tcl

Library: Snack

<lang tcl>package require sound

fconfigure stdout -buffering none puts -nonewline "How long to wait for (seconds): " gets stdin delay puts -nonewline "What file to play: " gets stdin soundFile

snack::sound snd snd read $soundFile after [expr {$delay * 1000}] {snd play -command {set done 1}} vwait done

catch {snd stop} snd destroy puts "all done" exit</lang>

XPL0

Works on Raspberry Pi. <lang XPL0>int Time, I, J, Ch; char FN(80), Ext; [Text(0, "Number of seconds to wait? "); Time:= IntIn(0); Text(0, "Name of mp3 file to play? "); I:= 0; loop [Ch:= ChIn(0); 

       if Ch = \CR\$0D then quit;
       FN(I):= Ch;
       I:= I+1;
       ];

Ext:= ".mp3"; for J:= 0 to 3 do 

       FN(I+J):= Ext(J);

There is no built in sound support so this example is coded for my Linux box. A change: rather than seconds to wait, a time is used. <lang zkl>hms :=Time.Date.parseTime(ask("Time to play mp3 file: ")); file:=ask("File to play: ") + ".mp3";

time:=Time.Clock.localTime.copy(); time[3]=hms[0]; time[4]=hms[1]; time[5]=hms[2]; time=Time.Clock.mktime(time.xplode()) - Time.Clock.time;

println("Play ",file," in ",time," seconds"); Thread.Timer(System.cmd.fp("mplayer "+file),time).go(); // a thread Atomic.sleep(time+1); // veg out until sound plays, then exit //to just play the file, no threads: //Atomic.sleep(time); //System.cmd("mplayer "+file); </lang>

Output:
$ zkl ding
Time to play mp3 file: 8:23pm
File to play: ding
Play ding.mp3 in 45 seconds
