[LAD] Help with resampling algorithm

Hi everyone,  I am hoping this is the right place to post this question. I am trying to implement the resampling algorithm as described in this paper: https://ccrma.stanford.edu/~jos/resample/resample.pdf I managed to construct the h (windowed sinc) table, and I have implemented the loop. I am having a hard time to compute the eta interpolation factor and the l index index for the h table. The "fixed point" implementation of the paper is a bit confusing to me. Looking at figure 7 in the paper, I think the interpolation factor needs to be computed between the h entries instead of between the original samples. However I don't understand how to compute the starting point (h(l)). I have just started working with audio code, so I might be misunderstanding something fundamental about the paper. I have coded a prototype which is shared here: https://gist.github.com/theWatchmen/746f35c349748525b412cfd9466608ce Apologies in advance if this is not the right forum. Marco
