mvm - music video maker

mvm is a little utility that will generate a video with an imperfect EQ of your incoming audio.

Order of operations:

1. mvm takes a WAV file as input
2. Creates a spectrogram from wav data
3. Normalizes spectrogram
4. Then draws shapes for each frequency band to create a video with a unique EQ visualization
5. Renders shapes onto frames which are output in named order
6. Frames are sent to ffmpeg for rendering

Installing

Clone repo and run make.

You will also need ffmpeg installed.

Usage:

Usage of ./mvm:
  -bar-count int
        number of eq bars to render, more bars equals thinner bars overall. 32, 64, 128 are good places to start (default 64)
  -base-color string
        base color used to color the EQ bars, accepts a hex value (default "ffffff")
  -frame-dir string
        directory used for frame output (default "frames")
  -hpf int
        high pass filter, used to cut off lower frequencies which can overpower the bottom end of the visualization
  -input-file string
        The file to use for input to the music video maker (default "input.wav")
  -keep-frames
        whether or not to keep the frames output directory
  -output-file string
        file to write output to (default "output.mp4")
  -rainbow
        rainbow mode does exactly what it says, applies a gradient rainbow to the EQ
  -scale-factor float
        adjust this value to change the shape movement, you may want to up the hpf when upping scale-factor
  -smoothing-size float
        smoothing size, attempts to smooth out movement between frames (default 0.5)
  -window-size int
        sample window size (default 4096)
