VideoWave

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.

Requirements

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:
