Python Tkinter audio player

Last update on April 25 2025 12:52:54 (UTC/GMT +8 hours)

Write a Python program that creates a simple audio player using Tkinter. Allow users to open and play audio files (e.g., .mp3, .wav).

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import filedialog
import pygame

class AudioPlayerApp:
    def __init__(self, root):
        self.root = root
        self.root.title("Audio Player")

        # Create buttons for opening, playing, pausing, and resuming audio files
        self.open_button = tk.Button(root, text="Open Audio File", command=self.open_audio)
        self.play_button = tk.Button(root, text="Play", state=tk.DISABLED, command=self.play_audio)
        self.pause_button = tk.Button(root, text="Pause", state=tk.DISABLED, command=self.pause_audio)
        self.resume_button = tk.Button(root, text="Resume", state=tk.DISABLED, command=self.resume_audio)

        self.open_button.pack(pady=10)
        self.play_button.pack()
        self.pause_button.pack()
        self.resume_button.pack()

        # Initialize pygame
        pygame.mixer.init()

        # Register a callback to stop audio when the window is closed
        root.protocol("WM_DELETE_WINDOW", self.on_closing)

        # Initialize playback state
        self.paused = False

    def open_audio(self):
        file_path = filedialog.askopenfilename(filetypes=[("Audio Files", "*.mp3 *.wav")])
        if file_path:
            self.audio_file = file_path
            self.play_button.config(state=tk.NORMAL)

    def play_audio(self):
        pygame.mixer.music.load(self.audio_file)
        pygame.mixer.music.play()
        self.play_button.config(state=tk.DISABLED)
        self.pause_button.config(state=tk.NORMAL)

    def pause_audio(self):
        pygame.mixer.music.pause()
        self.pause_button.config(state=tk.DISABLED)
        self.resume_button.config(state=tk.NORMAL)
        self.paused = True

    def resume_audio(self):
        pygame.mixer.music.unpause()
        self.resume_button.config(state=tk.DISABLED)
        self.pause_button.config(state=tk.NORMAL)
        self.paused = False

    def on_closing(self):
        # Check if audio is currently playing
        if pygame.mixer.music.get_busy():
            # Stop audio playback before closing the application
            pygame.mixer.music.stop()
        self.root.destroy()

if __name__ == "__main__":
    root = tk.Tk()
    app = AudioPlayerApp(root)
    root.mainloop()

Explanation:

In the exercise above -

The application allows users to open and play audio files (e.g., .mp3, .wav).
It uses the Tkinter library to create a graphical user interface (GUI) with buttons.
When the "Open Audio File" button is clicked, it opens a dialog box for selecting an audio file. The selected file path is stored.
The "Play" button loads and plays the selected audio file using 'pygame'.
The "Pause" button pauses audio playback, and the "Resume" button resumes it. These buttons are enabled and disabled based on the playback state.
The "on_closing()" function handles window closure. If audio is playing, it stops playback before closing the application.
The 'pygame' library manages audio playback, including loading, playing, pausing, and resuming.
The pygame.mixer.init() initializes the 'pygame' audio mixer.
The pygame.mixer.music.get_busy() function checks if audio is currently playing.
The GUI is created using Tkinter widgets (buttons) and packed within the main application window.
