       | Found this today when looking for something to turn short podcast
       | clips into something more visual. Anyone have any other open
       | source tools they like? I've heard of using ffmpeg
       | (https://lukaprincic.si/development-log/ffmpeg-audio-
       | visualiz...).

         | you are set.

         | audiogram, it will convert the audio/video you uploaded to text
         | and create an audiogram.

         | I had ended up using ffmpeg a few times for this (i think
         | inspired by the link you gave there) because it's often easier
         | to share video than just audio on mainstream social media
         | 
         | A few details of what worked for me and the output shown here:

         | But Astrofox looks much cooler and massively more
         | sophisticated.

       | Slightly reminiscent of old school demo scene stuff. Or perhaps
       | like a static version of WinAMP? I want more scrollers to greet
       | peeps in trippy space tunnels! xD

       | Digression about the Atari demo scene: Amazingly they still keep
       | cranking them out! https://www.youtube.com/watch?v=3QginSr9V7A

       | The one thing that I would like to see added to this would be the
       | implementation of IO streams for audio and video. I'd love to
       | find a piece of software that could be selected as the sole
       | output for either a system's audio or a specific application,
       | keep a buffer of the audio stream for processing, create an AV
       | output, and then allow that to either be captured or streamed to
       | something like OBS or VLC. Realistically, I can see latency being
       | a bit of an issue of course. Audio fidelity may also take a hit
       | if you exceed the buffer's capacity, but trying to implement a
       | direct passthrough for the audio may desync the it from the
       | visualizer.
       | 
       | Maybe it's just a pipe dream, but has anyone created/worked with
       | a project like that before? I'd be interested in seeing what's
       | out there.

         | Unfortunately this appears to be an Electron app, so expecting
         | behavior which would probably be quite simple for a real
         | application does in fact seem unlikely.
         | 
         | Too bad, too, since this does indeed look like a cool app.

       | Is there a package like this that renders real-time rather than
