When streaming an audio data of 32bit to a 24bit capable soundcard via ASIO, how does the hardware/drivers handle it? Are the excess bits truncated or dithered?

(I use ESI Juli@ souncard)

I think that IgorC was just trying to point out that it doesn't matter how you get from 32 to 24 bits because the DAC noise will swamp any differences.
OK, but that should be made clear, and anyway, that fact doesn’t negate the original question on a technical level.

An even more abstract post, which, for readers not privy to the arithmetical operators of C and C++, represents a calculation that shifts an input number 8 bits to the right, discarding each least significant bit that is pushed out.
