    It is my (non-first hand) understanding that these are created by using two 24 bit converters, where the low range ADC is used by default.  The high range ADC (attenuated by 48 dB, thus an upper 8 bits) is switched in when a peak exceeds 0dBFS.  Their intended use was for movie audio recordings where explosions and such would be troublesome to capture while still being able to capture low level dialog.

    I assume the conversion to FP is handled by an FPGA or ASIC chip.  I admit to a fair amount of conjecture in this post…
