how to resample audio from 44.1 HZ to 48 HZ

Can you tell me how to resample the audio from 44.1 hz to 48 hz in the block-wise way?

I used the multi-rate filter and the sample code from the IPP book.
The quality was not good and the transition between blocks seemed not smooth and I could hear clicking effects.

Any sample code would be appreciated. Thanks.

We used to use ippsResamplePolyphaseFixed_16s in IPP6.0, but since the new IPP7.0.2 does not include it, we would like to replace it with other method. I think we may need to use the multi-rate filter. Does anyone know how to repace ippsResamplePolyphaseFixed_16s by something else on a one-to-one base? I would like to implement

ippsResamplePolyphaseFixed_16s()
{
; multi-rate filers
}

Many thanks in advance.
