Galaxy S4 "sound and shot" feature - extract sound The Galaxy S4 has a neat feature called "sound and shot" (maybe "sound &amp; shot"?). It will let you record up to 9 seconds of sound with a picture. 

However, I want just the sound out of a picture I took, and I cannot find how to do that. There is no intuitive way to do this in the current version of Android or the gallery app. I know they must be storing the sound file somewhere, but apparently it is not next to the picture. 

This article explains that it is not possible to listen to the sound on anything but an S4. Seems kinda short-sighted to me.

My guesses are they implemented by either:


storing the sound hidden within the .jpeg itself or 
they have a separate hidden place they put a .wav or .3gp file or something. 


I have searched the phone for the latter, and cannot find it. Given that the file size is almost double a normal photo sitting right net to it, I am inclined to think it is buried in the .jpeg file. 

Any guesses as to how to get that out? and what the file format is?
When using "Sound &amp; shot" mode with the Samsung Galaxy S4 camera, the audio is stored as a WAV file that is embedded into a metadata tag within the JPEG. Here is how to extract the audio using ExifTool on a computer (not android). ExifTool can run on Unix platforms, Macintosh OS X, and Windows. If you are running linux, it might be available through your package repositories.

1) Install ExifTool on your computer.

2) Transfer the file of interest to your computer for extraction. (I'll leave that part up to you)

3) Now extract it. In my example, we assume the filename is called '20160520_061539.jpg', and the operating system is linux. You might have to  make adjustments to the process for other operating systems. In my case, the name of the tag which stores the audio is 'EmbeddedAudioFile'. To extract it, open a terminal and do:


  exiftool -b -EmbeddedAudioFile 20160520_061539.jpg > 20160520_061539.wav


You should now have a WAV audio file called 20160520_061539.wav in the present directory.
