Question about the 64-bit float

[TNM]

so you do dither to 24 bit.. interesting...

I suppose it makes sense since engine is 32/64 bit float.

What dither do you prefer? Off topic i know so if you feel it's too OT and could PM me.. I generally always use ozone megabit max in twisted wave or audition.. but never thought about it in PT...

Re D/A converters, in my case i only use a stereo monitor out on the apollo 8.. I don't do any summing back to analog..

I've been using GHz lately.

There are contradictions in all the answers on this thread. I try a synthesis with all: the 64-bit floating point is in Pro tools (HD or non-HD) if the plug-in require it. So, Cubase-Nuendo, Studio One, Logic Pro do not offer more (except marketing). Only Samplitude offers more (more than 64 bit float, around 80). Exact ?

I don't know that Samplitude is the only host offering 80-bit float mixing. It depends on CPU capability. Intel allows up to 80 and I assume the Magix folks simply allow whatever the CPU allows.

Every plug-in is a little app. that uses its own math. Algorithmix sold DX/VST2 plug-ins that do 80-bit float calculations.

The classic x86 FPU double precision instructions are working on 80 bits internally anyhow. Newer SIMD floating point double instructions operate internally at 64-bit.... so any developer who wants to claim 80-bit bit floating point handling can do this today,... with a trivial effort to make it slightly true... but they might well be better off coding to use the x86 SIMD/SSEn instructions for efficiency/vector capabilities. I therefore would not just assume any vendor bragging about 80-bit support really means anything.

This whole thread is a serious waste of time, plugin developers who need to are already dealing with this just fine. All the rest of us can go back to sleep...
