To extract audio from a video file using Python, you can use the pydub library. The following is a step-by-step process to extract audio from a video file:
Install the pydub library by running the following command in your terminal or command prompt:
pip install pydub
Import the required modules:
python
Copy code
from pydub import AudioSegment
Load the video file using the AudioSegment.from_file method:
python
Copy code
video = AudioSegment.from_file("video.mp4",format="mp4")
Use the export method to save the audio as a separate file:
python
Copy code
video.export("audio.wav", format="wav")
Here is the complete code:
python
Copy code
from pydub import AudioSegment
video = AudioSegment.from_file("video.mp4",
format="mp4")
video.export("audio.wav", format="wav")
In this code, the video file is loaded from the file video.mp4, and the extracted audio is saved as a WAV file named audio.wav. You can change the file format to any other audio format supported by pydub library such as MP3, OGG, etc.
Complete code
Here is the complete code to extract audio from a video file using Python and the pydub library:
python
Copy code
from pydub import AudioSegment
# Load the video file
video = AudioSegment.from_file("video.mp4",
format="mp4")
# Save the extracted audio as a separate file
video.export("audio.wav", format="wav")
In this code, the video file is loaded from the file video.mp4, and the extracted audio is saved as a WAV file named audio.wav. You can change the file format to any other audio format supported by the pydub library, such as MP3, OGG, etc
Method -2
Another way to extract audio from a video file using Python is by using the moviepy library. This library provides a convenient wrapper around the FFmpeg tool, which is a popular multimedia framework. Here is the code to extract audio from a video file using moviepy:
css
Copy code
from moviepy.video.io.VideoFileClip import
VideoFileClip
# Load the video file
video = VideoFileClip("video.mp4")
# Extract the audio from the video
audio = video.audio
# Save the audio as a separate file
audio.write_audiofile("audio.wav")
This code will load the video file from the file video.mp4, extract the audio, and save it as a WAV file named audio.wav. You can change the file format to any other audio format supported by the moviepy library, such as MP3, OGG, etc
