There are many utilities that display a scrolling spectrum waterfall plot [1] from a signal, but I was unable to find any open source utility that converted an audio file into a video file with a scrolling waterfall plot + the audio.

The SoX [2] sound utility can generate a static spectrum waterfall plot image from an audio file (or part of it), but it cant make a video. So I wrote a script to do this.

Its a very brute force approach. It requires lots of CPU time and lots of temporary disk space. The script depends on SoX, GNU Parallel, mencoder (or ffmpeg). GNU Parallel is optional, but will result in significant speed up on a multi-core system.

To use, create an empty directory on a volume with plenty of disk space and run with the audio file as a parameter.  Eg:

./make-spectrogram-video.sh -t "My Music File" mymusic.mp3

The output will be written to output.avi and output.mp4. Other options include setting frame rate, the speed of the scrolling, audio credit text etc. To get full help do this:

./make-spectrogram-video.sh -h

The script is available on GitHub here [2]. Here is a sample output video of Bachs Toccata and Fugue in D Minor [3] :
