![]() Once into the digital domain and converted to floating point, one can thenceforth essentially ignore signal levels and gain, right up to the point where she signal goes back to non-floating-point, or to analogue at the amplifiers/speakers. So whether integer, fixed point, or floating point, one definitely still needs to set the front-end gain/level sensibly. It's possible to do better if money is no object. Even achieving that with a mic pre-amp as well is a real challenge (e.g., Focusrite show ~110dB dynamic range on their 18i20). ![]() A quick look at Cirrus and Burr Brown ADCs shows none better that 127dB SNR. Both of those still need attention to getting the levels sensible and getting the signal into its initial digital format (invariably, I think, non-floating). ![]() The weakest links in the chain with floating-point like this are the pre-amps+ADC at the front and the DAC+PA+Speakers at the back, and the article glosses over that a bit. ![]()
