Hi Poppa, Just a couple of clarifications for you from my life time Friend tom Graefe who was on the Sony Oxford console design teem. :) Heres a couple of quick pointers to remember when tracking. First 24 bit is the resolution of the A/D converter. Yes theoretically the Dynamic range of 24 bits is 144 dB. The reality of usable range is substantially less. That 140+dB has nothing to do with volume or sound pressure level. You should always record to maximum level before clipping to get the maximum signal to noise ratio when recording individual tracks. As you get further away from 0dBFS you start showing up more of the non linearities of the A/D process. This is especially noticeable at very low levels. There is no need for headroom when recording Digital. This is not tape. The A/D is most linear and least artifacts just before 0 dBFS. When designing a system you measure the IMD, Signal to Noise etc. of an A/D at -1 dBFS. Sometimes at -0.5 dBFS.
