@BartWronski@theWarhelm@demofox the paper is describing a method to sample the output at an arbitrary time. The implementation (from my skim of it) effectively upsamples the signal using a fixed filter, then uses linear interpolation between these output samples. I might not be fully understanding the question but happy to chat through it.
If t is a fractional time at the higher rate, l is the integer part of time modulo the upsample rate and n is the fractional part.
