You might want round here and potentially cause an error if it's not very close to an integer decimation with a warning to explain to the user that they do need to use a power of 2 or at least something that evenly divides.

I made one minor comment, but otherwise, I think this looks good.

Are you fine with how I named the variables or is there something more intuitive |

This is tested with the base inspiral code, It is not perfectly matching all of the triggers but it is in the ballpark

For reference the base 2048 inspiral and fir code produce consistent results |

The logic of the function remains the same the main difference is utilizing a larger buffer to perform the fft and the reslicing back into desired sample rate done at the end.
This only works for sample rates of the engine that is less than the rate of the tap construction.
