int -> float -> int conversions?

hackborn · ‎01-27-2005

Hi there,

I've been poking into the IPP and it looks like it has a lot of great functionality, but I don't see a way to handle my immediate issue: I'm writing an ASIO driver and I'd like fast routines for converting from the various ASIO formats (things like int32 LSB/MSB, int 16 LSB/MSB, etc.) to floats (ranged -1 to 1) and then back again. Does anyone know how to do this?

thanks much,
eric hackborn

Hi,

I'd recommend you to take a look on IPPS Manaul. We have bif ippsConvert functions family,like

ippsConvert_16s32f

ippsConvert_32s32f_Sfs
