A good friend and his wife recently founded an AI startup in the lifestyle niche that uses machine learning<\/a> to discover specific real-world patterns from videos.<\/p>\n

For their business system, they need a pipeline that takes a video file, converts it to audio, and transcribes the audio to standard text that is then used for further processing. I couldn\u2019t help but work on a basic solution to help fix their business problem. <\/p>\n

In this short project tutorial, I\u2019ll share my code solution to convert a video to audio<\/strong>, i.e., extracting a .wav<\/code> file from a .mp4<\/code> file.<\/p>\n

\"\ud83d\udc49\" Given:<\/strong>\n.mp4<\/code> video file \"\ud83d\udca1\" Required:<\/strong>\n.wav<\/code> audio file<\/pre>\n
Use Python to accomplish this programmatically! \"\ud83d\udc0d\" <\/p>\n

You can convert a video file to an audio file as follows. First, create a function that takes the location of your input video file as the in_path<\/code> parameter and the location of your output audio file as the out_path<\/code> parameter. Second, install and import the moviepy<\/code> library to read the video file and write out the audio file in the .wav<\/code> format.<\/p>\n
import moviepy.editor as mp def video_to_audio(in_path, out_path): \"\"\"Convert video file to audio file\"\"\" video = mp.VideoFileClip(in_path) video.audio.write_audiofile(out_path) # Video to audio\nvideo_to_audio('sample_video.mp4', 'sample_audio.wav')<\/pre>\n
Before this code runs without error, you first need to pip install moviepy<\/code> in your environment. For instance, if you run Python 3.10, you’d probably have to run pip3.10 install moviepy<\/code>. More here:<\/p>\n

Alternative Using Subprocess<\/h2>\n
Using Python, you can convert a video file to an audio file by using the subprocess library. First, store the location of the input video file in the in_path<\/code> variable, and the location of the output audio file in the out_path<\/code> variable. Then, call the subprocess.run()<\/code> method with the command line parameters to convert the video file to an audio file. The output audio file will be in the .wav<\/code> format.<\/p>\n
import subprocess in_path = 'sample_video.mp4'\nout_path = 'sample_audio.wav' subprocess.run([\"ffmpeg\", \"-i\", in_path, out_path])<\/pre>\n
