Is there an audio equivalent of eidetic memory? In this YouTube video by The Blaze it is claimed that Ted Cruz has "audiographic" memory. He does seem to have quite a good memory based on videos I've seen of him, but I'm not sure if Glenn Beck is exaggerating and I can't find the Wall Street Journal article he's referring to.

I know about eidetic memory (photographic memory):


  ... is an ability to vividly recall images from memory after only a
  few instances of exposure, with high precision for a brief time after
  exposure, without using a mnemonic device.


Is there something similar for audio exposures and recall? Audiographic memory does not seem an academic term. Is this phenomenon discussed in academia?
I have been doing some research and this is what I found so far. 

First, the memory of sounds is called echoic memory (Alley Dog; Echoic Memory Definition) and is a form of sensory memory. This means that by nature, it is short-term.

However, I found an interesting wikipedia article, followed the source, and found that, in fact, it appears that eidetic memory also includes remembering sounds! (Taylor;  Encyclopedia of Human Memory; Superior Autobiographical Memory; p.1099).
So it could be that there isn't a term for it because it is included in this.

When it comes to 'audiographic memory', a thorough search leads me to thinking that indeed, it's not an academic term and is not researched or discussed as such. The only things I can find that use that word are of questionable validity (ex: Bates, Unconscious Processes, 2009).

For some reason, the video link does not work for me, but I hope that this information makes things clearer for you!
