Write 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, copy the MP3 to the app folder you set up. Then, when the app asks you for the filename, you type in the name without an extension.

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.

        if err := scanner.Err(); err != nil {

Liberty BASIC

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.

prompt "MP3 to play as alarm"; mp3$

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 [https://docs.python.org/3.4/library/wave.html 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 3.4.1

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")

Racket

Racket does not currently have native mp3 support, so this example uses system to call an external application.

#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")))

REXX

Using SLEEP

/*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.*/

'''output''' when using the input of: xxx

Using spin

/*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.*/

zkl

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.

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);

Output:
