This small application creates a sound wave and superimposes it on each frame of a video.

Check a small description of its inner workings in its original post.

• ffmpeg to handle video encoding/decoding
• opencv to create the visuals (waves)
• scipy to get the spectral information of the audio
• numpy to handle the data
• Matplotlib is not really needed, but shows the intermediate data, if you want to know what's happening behind scenes.

from VideoWave import Waver
wave_clip = Waver("clip.mp4")
wave_clip.export("new_clip.mp4")

And that's it. You have now a new clip with audio waves on top of the image looking like this:

You can install the latest version of VideoWave directly from the repository using git and pip:
