Hi Rick.Thank you for the list of papers with stable realizations. I have briefly looked at all the methods and decided to stick to the mSDFT.I will use that for...

We are talking about the SDFT which can be realized as:For me, the goal is obtaining the exact same output as using a SDFT but without stability issues.I have accepted...

Hi kaz.I might be wrong but what you are describing seems like the basic SDFT. Then you suggest substracting mean of the previous frame from the accumulator. Does...

I want a sliding algorithm as it is not necessarily each block but could be any time I want the output. Also, the length N will be much greater than the block size,...

Thank you for the inputs.As I wrote, it was also my thought that non-integer coefficients would lead to instability. However, in the "Musical applications of microprocessors"...
Is it possible that a Chamberlin state variable implementation of the Sliding Goertzel (SG) resonator provides a stable implementation without introducing a dampening...
