Linearly interpolated fractional delay is equivalent to filtering andresampling a weighted impulse train (the input signal samples) with acontinuous-time filter having the simple triangular impulse response In discrete time processing, the operation Eq.(4.5) can beapproximated arbitrarily closely by digital upsampling by al…

A complex tonal input being resampled using 8-tap polyphase filters (left) and linear interpolation (right). The input signal to the above output was a set of tones separated by octaves in frequency. The aliasing components of the spectrum have introduced inharmonic audible distortions in the linear interpolation case.

Start with a simple linear interpolation: instead of setting cbuf[z] to sampdata[i], set it to sampdata[i] + (j/(double)a)(sampdata[i+1] - sampdata[i]). I don't know enough about sound processing to know if that's even near sufficient, but it'll keep you busy until someone comes along who knows their stuff :-) You may also need to anti-alias the downsample.
