Yes you will need 64 bits, but only once...

That convinces me that I don't need to search for a 32-bit DAC, much less a 64-bit DAC.     2 atmospheres... Sounds a bit like you're referring to the loudest possible sound in air, 194 dB? 24 bits won't take you to more than 144 dB. And since even 32 bits give a futile 192.6 dB, it seems like the next level will be needed: 64 bits. ;-)   /mr
