Digital music with that much of dynamic range (50db) means for 99% of the amplifiers you can barely hear the sound unless volume cranked all the way.
30dB is already on the upper end of recordings.
The thing is every 3dB in loudness you need to double the power. 20dB to 50dB is basically 1000 times the power difference.
Digital unless analogue has defined maximum level which is 0dBFS. Word like transient is just BS.

Honestly... on a (poorly dithered) CD, 50 dB is more than halfway to the noise floor.

Is there a way to actually analyze audio conveniently for dynamic range, transients, etc.?

This is the track given in Audeze's example above:

Does it actually have the aforementioned 50 dB above average transients? If it doesn't was Audeze lying or just giving an extremity of the range that was tangential to the gist of their argument? What kind of audio content would then have a 50 dB above average transient? Some sort of scientific recording of an explosion? To their example you would have to be listening at 80 dB average to experience the maximum recommended 130 dB transients on their drivers. They are certainly capable of that range with some of the lower impedance ones achieving that at only 1W.

Far from it.

Thanks. I don't really know how to interpret this, but where exactly is this from? Would it benefit to have a player or software that can categorize your library with this data in the background or on the fly? Or is most music compressed enough that it doesn't matter these days?

This is from Izotope RX. It means that transients go up to 20 dB over the average level. Not 50 dB.

Most audio players should have some form of loudness equalization nowadays.
