resampling options

Could someone provide a simple example of resampling a float array?

For example, I have an array of 1024 floats sampled at 48kHz... and I want to upsample or downsample to say 41kHz or 96kHz, etc... using the HDC is obvious enough, but I'm not sure which ipp function is best in terms of performance and simplicity. The example in the ipp book meets neither of these.

It seems using the FIRMR functions seems to make sense since I obviously want to filter the output to interpolate for any zeros inserted, but I see there are also resampling functions in the speech libraries too... are these easier? faster? A really basic example would be most appreciated.

Thanks :)
