| CUBASE and probably all other 32bit-float systems are using (+1 to -1) value range.
And 32bit float has a linear precision dynamic range by 150dB = log10(2^25)*20.
And it's all up to the Plugin creator to use 80bit-float or something so the plugin won't affect the dynamic range badly.
ProTools TDM uses 48bit between plugs that are on the same TDM bus and DSP, so the transfer between PLUG-INS is 289dB.
The weakest point in that system should be the PANNING/FADER/SUMMING MIXER.
But if they're all done in the same calculation in the FPU you should have 80bit-float (INTEL x87) and that makes it =log10(2^65)*20=391dB.
And that 80bit is used in every calculation in the computers FPU, but it can be rounded down to 64 or 32bit float when being outputted.
Just to make a comparison with ProTools TDM system the SUM MIXER is at 48bits = 289dB.
