Audio/aac =AAC
audio/aacp =AAC+/HE-AAC
Be aware, though AACv1 hss way worse efficiency, then both HE-AAC and HE-AACv2 (both usually bo by aacPlus as a brand name)

Though, chrome is actually supposed to work with aac and aac-plus on windows only when it's insode an mp4 container and not when transmitted without any container .

Thanks Mastacheata, I'm editing my answer since I've been doing some trial and error and I see the audio plays fine inside a container like the following:



I tested in Chrome (Android and Ubuntu) and also in Safari. The stream played smoothly in the three platforms.

Audio formats are still a hassle on the web, especially with streaming music as that's not really what the audio tag was supposed to do nor is Shoutcast or any radio streaming for that matter technically considered streaming. (You can see in video streams like youtube, that the browser will receive the stream in chunks while the audio in Shoutcast is basically just an infinitely long audio file that is constantly downloaded from the web)
