Will Samplitude Go To 64bit Like Sonar And Cubendo?

Recommended Posts

Well, they deliver 24bit AES words nevertheless.

PS: the word "patent" in this product does not refer to anything that provides the resolution uttered. Gainstaging is an old principle and some approaches to have it patented were already been dwarfed in the last decade.

Hi Sebastian and David,

The Neumann digital mic ADs don't use just a gainstaging design. They use two converters simultaneously, hoever one of them fed by a signal which first runs through a non-linear analogue stage! At the end the results of the two converters are calculated together in an appropriate way.

Ulrich

Hi Ulrich,

The "non-linear analogue stage" doesn't accidently happen to be an amplifier, does it?

Sebastian

Hi Ulrich,

I'm guessing the "coarse" ADC could then have larger steps at larger signal amplitudes, which could yield the same dynamic range as 28-bit LPCM. It would have much larger quantization error for large signals (which I observed), but that could still be tolerable on a percentage basis. The "fine" ADC would be used near zero, to prevent crossover distortion. There are other interesting things one can do with two ADC's, such as pipeline conversion, but I think Neuman's choice avoids a very difficult linearity adjustment process: below a certain signal level their design probably reverts to a single ADC outputting LPCM, with no special adjustment required.

Now to call it a "28-bit" ADC... well, you can't ever turn your back on those marketing folks! :angry:

People are confusing calculation bits with memory addressing bits.

A modern CPU is already capable of doing 80 bit calculations with a 32 bit OS and software. This is not going to change with 64 bit memory addressing.
