My "studio" is in a quiet neigbourhood with no traffic, no AC, no appliances running and still the ambient noise is around 30 dB, mostly low frequences from somewhere. You should always measure with C weighting, or all the low rumbles are not ... more

Actually it is possible to get over 100 dB of dynamic range on a 16 bit CD. Dither is the magic word. Without dither the theoretical maximum is 16x6.02 dB + 2 dB or so (forget the exact additional number) = 98.3 dB aprox. To find a performance (and recording venue) where this is possble to achieve and record is another matter. I do not know of any ... more
