You were comparing audio cards, so of course you can't be discussing anything but audio cards. They aren't involved in mixing.
Seeing that no computer has 24 bits data type, of course everything is done using 32 bits float (which has a 24 bits mantissa anyway). And seeing you're dealing with numbers with a value between -1 and 1, you're 32 bits floats are the same as 24 bits int accuracy wise.
FWIW, even for 16 bits audio output, on all OS but Android, you use 32 bits floats.
And none of it got anything to do with the audio card you're using at this stage.
The bit rate of the audio card was never the essential point on why you should pick a DAC vs using the one in your motherboard. (Please read my previous post #843 on this subject.) Several 16 bits DAC sound much better than other 24 bits DAC which is also why I suggested getting a used benchmark DAC1 ( 24 Bit ) over any new consumer type product or DAC motherboard ( 32 bit ).
This being said, I believe that more and more recordings in the future will be done, processed / Mixdown / Mastered at 32 bit due to the huge head room you acquire also allowing you "unclip" some files if necessary. Several test are done on youtube where you can clearly hear the differences. Now, if I understood you correctly, what you are saying is that you believe that any 32bit audio files (recorded and processed ) result in the same listening experience whether it is converted back to a 16/24bit DAC or kept intact at 32 bit?. Which DAC and what test?
The other reason I'm doubting this fact ( it is still possible ) is because when the same file recorded at 16,24 or32 bit is converted down to MP3 or AAC format, the difference is noticeable.
PS : I think we are drifting away from the subject of this thread, so if you do not mind, I'd respectfully like to put an end to it. Thank you. Too many threads/debates on the net about this . it's does not seem to go anywhere
