Python implements a simple audio player

1. The Python library that needs to be used

• pygame
• tkinter

2. Simple UI design

audio_player = Tk()
audio_player.title('Audio Player v1.0')
audio_player.geometry('100x100+570+200')
audio_player.maxsize(height=110, width=220)
audio_player.minsize(height=110, width=220)

3. Realization of functional modules

3.1 Select an audio file to play

def selectFile():
    file = filedialog.askopenfile(mode='r', filetypes=[('AudioFile', '*.mp3')])
    global filePath
    filePath = str(file).split("'")[1]
    try:
        playAudio()
    except:
        pass

3.2 Control audio playback, pause

def changeText(text):
    if text == 'play':
        return 'pause'
    if text == 'pause':
        return 'play'


def playStop():
    playBtn.config(text=changeText(playBtn.config('text')[4]))
    if playBtn.config('text')[4] == 'pause':
        mixer.music.unpause()
    else:
        if playBtn.config('text')[4] == 'play':
            mixer.music.pause()

3.3 Control audio volume

Here you can define a global variable x, initialized to the value 0.5.

def audioINC(y):
    mixer.music.set_volume(y + 0.1)
    global x
    x += 0.1


def audioDEC(y):
    mixer.music.set_volume(y - 0.1)
    global x
    x -= 0.1

3.4 Player initialization and other details

def playAudio():
    try:
        mixer.init()
        mixer.music.load(filePath)
        mixer.music.set_volume(x)
        playBtn.config(text='pause')
        mixer.music.play()
    except:
        pass

4. run

frame = Frame(app)
frame.place(x=35, y=20)

openBtn = Button(frame, text='OpenFile', command=selectFile, width=8).grid(row=0, column=1)

audioDec = Button(frame, text='➖', command=lambda: audioDEC(x)).grid(row=1, column=0)
playBtn = Button(frame, text='...', command=playStop, width=8)
playBtn.grid(row=1, column=1)
audioInc = Button(frame, text='➕', command=lambda: audioINC(x)).grid(row=1, column=2)
restartBtn = Button(frame, text='Restart', command=playAudio, width=8).grid(row=2, column=1)

app.mainloop()

5. Simple audio player display

①Click the "OpenFile" button to open the local audio file
②"➖" and "➕" respectively control the decrease and increase of the volume
③Click the "Restart" button to replay the currently selected audio

6. Summary

This article only implements a simple audio player, the UI is extremely simple, in order to realize the function of audio playback, it is only for learning reference.
