Hi there,
this is the second time that I get a similar response:
Are you sure that your DSP approach is sound?
If 64bits are not enough there is probably something wrong with
your algorithm.
I really don't want to sound arrogant because it is not what I am
about, however I ASSURE you that I performed all the necessary tests,
both mathematical and auditive to corroborate my conclusion. My
approach is sound, I just don't have enough bits for the audio
quality I am after. I understand it might sound weird to hear that 64
bits are not enough. I might have reached the upper limit of the
current technology, but doubting my approach is not helping. I would
ask advice on the approach if I wasn't sure it was the right one.
I would love to get back on track with the questions I have asked. I
apologize in advance if I offended somebody. It was not my
intention.
I suspect only those possessing a 128bit dac are in a position to
comment, in the absence of a description of exactly what you are trying
to do.
In the meantime, there is always:

etc etc etc...
Probably leaves the FPU way behind, so YMMV.
