Example

r, err := speexdsp.ResamplerInit(2, 48000, 44100, speexdsp.QualityDefault)
if err != nil {
	panic(err)
}
defer r.Destroy()

var inpcm []int16
// fill "inpcm"

if readed, outpcm, err := r.PocessIntInterleaved(inpcm); err != nil {
	panic(err)
}

// "readed" contains number of int16 values read from "inpcm"/
// "outpcm" contains resampling result (length may differ from "inpcm")
