Simple audio resampling

Hi All,

I looking to do some simple audio re-sampling of 16-bit data from 48k to 44.1k. For example, I have 6400 input bytes and I want 5880 bytes out.

How can I do this with IPP? I looked at the ippsSampleDown_16s function, but this only does int factors, not floating point.

If I have to use an FIR filter, can someone point me to some sample code because it seems quite complex from the docs.

Thank you!

Hi,
you can try using ippsResamplePolyphase_* or ippsResamplePolyphaseFixed_* function
Thank you
