New audio visualization filters

Jun 18, 2015

MLT developer, Brian, developed 4 new filters, available now in git master. The fft filter uses the fast Fourier transform to produce data for other filters. The dance filter moves, scales, and rotates an image or video in reaction to the audio characteristics. The lightshow filter alters the color of the image based on the audio. Lastly, the audiowaveform filter draws a waveform over the image.

These were all sponsored by the "Learn Your Lyrics" YouTube channel. They generate the videos using MLT through shell scripts that generate long melt command lines. You can see the fft, dance, and audiowaveform filters in action in this video:
