There's an HDR war brewing on TikTok and other social apps. A fraction of posts that use HDR are just massively brighter than the rest; the whole video shines like a flashlight. The apps are eventually going to have to detect HDR abuse.

Just what we need, a new loudness war, but for our eyeballs.

What if they did HDR for audio? So an audio file can tell your speakers to output at 300% of the normal max volume, even more than what compression can do.

HDR audio already exists in the form of 24-bit and 32-bit floating point audio (vs. the previous 16-bit CD standard). Volumes are still mapped to the same levels because anything else doesn't make sense, just as SDR content can be mapped to HDR levels to achieve the same levels of brightness (but not the same dynamic range, as with audio).
