hi every one 🖐
in this post i will show you how to add background music to the voiceover 🙂

step 1

you need to install moviepy

pip install moviepy

step 2

you need any voiceover and background music

if you haven't voiceover you can generate it using the pyttsx3 library for testing

You also get background music

import pyttsx3

def say(text):
    engine = pyttsx3.init()
    engine.setProperty('rate', 160)
    engine.save_to_file(text, 'test.mp3')
    engine.runAndWait()


say('this is text to test 123 and this is number' * 30)

step 3

Now I will merge the audio files using the CompositeAudioClip function

import moviepy.editor as mp

test_voice = mp.AudioFileClip('test.mp3')
music = mp.AudioFileClip('good-night-160166.mp3')

final_audio = mp.CompositeAudioClip([test_voice, music])
final_audio.write_audiofile('out.mp3', fps = 44100)

Thank you all 🙂❤
