Does it matter? There is no commercial player that can create an analog signal with anything like 24 bit accuracy. There still are no DACs that have anything like 24 bit accuracy.
I was under the assumption that even if you play 32bit float you will only be really playing 24bit integer...
24 bit integers only exist in the world of numbers. They don't exist in the world of real voltages or real sound pressures.
Also what is "Sound Pressure"?
Seems pretty self-explanatory!
Is Wikipedia broken where you are? ;-)
Also read the article on Sound Pressure Level.
My headphones have a its Sound Pressure listed as "104 dB (1mW/500Hz)" with a THD of less than 0.1%... what does that mean in terms of dynamic range?
The dynamic range in that spec comes from the "THD of less than 0.1%". 0.1 THD suggests dynamic range of 80 dB. Dynamic range is not just about how loud, but also about how clean.
THD of less than 0.1%
I looked up sound pressure and it seemed very similar in concept to dynamic range but with less focus on actual bit integers which was sort of confusing.[/quote]
It sounds to me like you may be getting lost in the numbers.
Dynamic range is not just about how loud, but also about how clean.
