>From G3PLX: Alberto: Thanks! That's the information I was seeking. It looks as if I was half-right, if there are, at best, 18 good bits in a 24-bit card. As Phil says, if 16-bit cards turn out to be worse that 16-bits, then there is some reason to go for a 24-bit card (which is worse than 24bits!). But for sure, 24 bit cards are not going to be 256-times (48dB, 8-bits) better than 16-bit cards.
I will now continue working to convert my own 16-bit SDR code to 24-bits, but I think I will add a button on the front panel which zaps the bottom 8 bits. It will be VERY interesting to see if it makes any difference. To take Frank's point, as far as I can see from both the ASIO and WMME interfaces, there IS an accessible point in the software where this can be done before the audio data becomes floating-point.
