... Somewhat older Support Forum post:

 Involves downloading --tvmode=hlshd and a hvf* mode with 320kbps audio, 
which now, with GiP 3.02, could be any; to save on bandwidth, 
choose the smallest available hvf mode for your pid... 

 To make it more transparent to you, 
"25fps.mp4" in the post means "720p25fps96k.mp4" and 
"50fps-audio.mp4" can just mean now, e.g., "320k.mp4" 
(does not have to be 50fps anymore... ). 
"out.mp4" would then be "720p25fps320k.mp4" 

 There are other means to just download the 320kbps 
audio stream (without an accompanying video stream) 
and then multiplex it with hlshd, but this involves 
tools other than GiP and is left 
for the more adventurous...
