Creating a Music Player with Python and PyDub

Ready to take your love of music to the next level? With Python and PyDub, you can build your own customizable music player. This guide will guide you through the process of creating a music player that meets your specific needs and preferences, from loading and playing audio files to creating a playlist and adding playback controls. Let’s dive in and create the ultimate music experience!

Introduction

Music is an integral part of our daily lives. We listen to music while working, travelling, and even during our leisure time. With the advent of technology, we have been able to access and play music more conveniently. However, sometimes the music player apps on our devices do not meet our preferences or needs. In such cases, we may opt to create our own music player. In this article, we will discuss how to create a music player with Python and PyDub.

Building a music player with Python and PyDub provides a customizable and personalized approach to enjoying music. Python is a widely-used programming language that enables you to create a music player that caters to your individual preferences. Meanwhile, PyDub is a powerful audio processing library for Python that simplifies working with audio files of various formats.

By building a music player with Python and PyDub, you have the ability to create a unique listening experience that meets your specific needs. Whether you want to customize the playback controls, create playlists, or add audio effects, this article will guide you through the process of creating a music player that puts you in control of your music. So let’s get started!

Setting up the Environment

Before we start building our music player, we need to set up our development environment. We will be using Python 3, so make sure you have Python 3 installed on your machine. You can download Python from the official website at https://www.python.org/downloads/.

We will also need to install PyDub, which we can do using pip, the Python package installer. Open your terminal or command prompt and run the following command to install PyDub:

pip install pydub

Once PyDub is installed, we can start building our music player.

Creating the Music Player Class

The first step in building our music player is to create a class that will handle all the audio playback functionality. We will call this class MusicPlayer.

from pydub import AudioSegment
from pydub.playback import play

class MusicPlayer:
    def __init__(self):
        self.playlist = []
        self.current_track_index = None
        self.current_track = None
        self.paused = False

In this code snippet, we import the required PyDub modules and define the MusicPlayer class. The init method initializes the class variables that we will be used to manage the playlist, the current track, and the playback state. The playlist variable is a list that will hold all the audio files that we want to play.

Adding Tracks to the Playlist

Now that we have created the MusicPlayer class, we can start adding tracks to the playlist. We will add a method called add_track that takes a file path as an argument and appends the audio file to the playlist.

def add_track(self, file_path):
    track = AudioSegment.from_file(file_path)
    self.playlist.append(track)

In this code snippet, we use the AudioSegment class to load the audio file from the file path and append it to the playlist.

Playing Tracks

Now that we have added tracks to the playlist, we can start playing them. We will add a method called play_track that takes an index as an argument and plays the track at the specified index.

def play_track(self, index):
    if index >= 0 and index < len(self.playlist):
        if self.paused:
            self.paused = False
            self.current_track = self.playlist[index]
            play(self.current_track)
        else:
            if self.current_track_index != index:
                self.current_track_index = index
                self.current_track = self.playlist[index]
                play(self.current_track)
    else:
        print("Invalid track index")

In this code snippet, we first check if the index is valid by making sure it is within the bounds of the playlist. If the index is valid, we check if the player is currently paused. If it is paused, we resume playback of the current track. If it is not paused, we check if the index is different from the current track index. If it is different, we set the current track index to the new index and play the corresponding track.

Pausing and Resuming Playback

We will now add functionality to pause and resume playback of the current track. In our ‘MusicPlayer’ class, we can add methods to allow the user to pause and resume playback of the current track.

To pause playback, we can add a method called ‘pause’ that sets the paused attribute of the MusicPlayer class to ‘True’. We can also save the current playback position of the track in the ‘pause_position’ attribute of the class.

def pause(self):
    if self.current_track is not None and not self.paused:
        self.paused = True
        self.pause_position = self.player.get_pos()
        self.player.pause()

In this code snippet, we first check if there is a current track playing and if playback is not already paused. If a track is currently playing and not paused, we set the ‘paused’ attribute to ‘True’ and save the current playback position of the track in the ‘pause_position’ attribute. We also pause the player to pause the playback.

To resume playback, we can add a method called ‘resume’ that sets the ‘paused’ attribute of the ‘MusicPlayer’ class to ‘False’. We can also use the play method to start playback from the ‘pause_position’ attribute.

def resume(self):
    if self.current_track is not None and self.paused:
        self.paused = False
        self.player.play()

In this code snippet, we first check if there is a current track playing and if playback is currently paused. If a track is currently playing and paused, we set the ‘paused’ attribute to ‘False’ to resume playback. We also call the ‘play’ method to resume playback from the position where it was paused.

By implementing these methods, we can easily pause and resume the playback of tracks in our music player. This can be especially useful when listening to long tracks or when interrupted and needing to quickly pause and resume playback.

Displaying Track Information

In addition to playing tracks, we also want to display track information such as the title, artist, and duration. We will add a method called print_track_info that prints the title, artist, and duration of the current track.

def print_track_info(self):
    if self.current_track is not None:
        print(f"Title: {self.current_track.tags['title']}")
        print(f"Artist: {self.current_track.tags['artist']}")
        print(f"Duration: {self.current_track.duration_seconds} seconds")
    else:
        print("No track playing")

In this code snippet, we use the tags attribute of the AudioSegment class to retrieve the track information such as the title and artist. We also use the duration_seconds attribute to retrieve the duration of the track in seconds.

Implementing a Command-Line Interface

Now that we have implemented all the required functionality, we can create a command-line interface to interact with our music player. We will add a while loop that prompts the user to enter commands and executes the corresponding method.

if __name__ == '__main__':

    player = MusicPlayer()

    while True:

        command = input("Enter command: ")

        if command == 'add':

            file_path = input("Enter file path: ")

            player.add_track(file_path)

        elif command == 'play':

            index = int(input("Enter track index: "))

            player.play_track(index)

        elif command == 'pause':

            player.pause_playback()

        elif command == 'info':

            player.print_track_info()

        elif command == 'exit':

            break

In this code snippet, we first create an instance of the MusicPlayer class. We then start a while loop that prompts the user to enter a command. We use a series of if statements to execute the corresponding method based on the command entered by the user. We also include an exit command to exit the while loop and terminate the program.
