Sorry for the Topic=Guan hehe it should have been Topic=Floating-Point  :laugh:

Anyway i mean Floating-Point in general not just 32 bit.

I'm pretty sure I read that XMPlay uses 64 bit integers, and the quote from BASS is "32 bit floating-point decoding and processing".  So I guess XMPlay also uses 32 bit floats, unless that quote from the BASS site is outdated...

All internal decoding/processing is in 32-bit floating-point, and it's only converted to the user-chosen output format at the end... I'm not sure if that's exactly what you were asking, but there you go anyway :D

Does 64Bit floating point improve sound quality?

You have to have an alien parasite sitting in your ear to notice the difference between 24 and 32, already.

Internally, the FPU does perform the calculations in 64-bit, but the results are stored by XMPlay in 32-bit... storing 64-bit results would be major overkill - the differences are so tiny that there's no way anyone can possibly hear any benefit (especially considering soundcards don't go above 24-bit :)), and is not worth the performance hit it would incur.
