MoviePy – Creating Audio Clip

In this article we will see how we can create a audio clip in MoviePy. MoviePy is a Python module for video editing, which can be used for basic operations on videos and GIF’s. Video is formed by the frames, combination of frames creates a video each frame is an individual image. Audio clip is similar to audio file clip but it is made using numpy array, it can be edited and altered any time.

In order to do this we will use AudioClip method

Syntax : AudioClip(make_frame, duration=3)

Argument : It takes method and duration as argument

Return : It returns AudioClip object

# importing editor from movie py
from moviepy.editor import *
  
# importing numpy
import numpy as np
  
# method to create a fram
def make_frame(t):
    numpy_array = np.array([1, 2, 4, 1, 3, 4, 5])
    return numpy_array
  
  
# creating audio clip
clip = AudioClip(make_frame, duration = 3)
  
# printing audio clip
print(clip)

Output :

moviepy.audio.AudioClip.AudioClip object at 0x00000269985E1F88
