https://dsp.stackexchange.com/questions/76449/how-would-i-approach-implementing-a-windowed-sinc-filter-with-changing-cutoff-in
ELI5 how to implement a windowed sinc FIR filter in real time for an audio synthesizer. The synthesizer may adjust the filter's cutoff by an LFO, and there are a lot of filters in use, so this is both not stored and required to be fast. I use a $48000Hz\times 288\times 12$ core clock frequency and a $40960Hz$ internal sample rate.
Windowed-Sinc Filters
https://www.dspguide.com/ch16.htm
Chapter 16: Windowed-Sinc Filters. Windowed-sinc filters are used to separate one band of frequencies from another. They are very stable, produce few surprises, and can be pushed to incredible performance levels. These exceptional frequency domain characteristics are obtained at the expense of poor performance in the time domain, including ...

Strategy of the Windowed-Sinc the idea behind the windowed-sinc filter. [see Figure 16-1] The frequency response of the ideal low-pass filter: All frequencies below the cutoff frequency, f C, are passed with unity amplitude, while all higher frequencies are blocked. The passband is perfectly flat, the attenuation in the stopband
Strategy of the Windowed-Sinc
http://www.dspguide.com/ch16/1.htm
Figure 16-1 illustrates the idea behind the windowed-sinc filter. In (a), the frequency response of the ideal low-pass filter is shown. All frequencies below the cutoff frequency, f c, are passed with unity amplitude, while all higher frequencies are blocked.The passband is perfectly flat, the attenuation in the stopband is infinite, and the transition between the two is infinitesimally small.
Windowed Sinc Interpolation - Stanford University

Windowed Sinc Interpolation. Bandlimited interpolation of discrete-time signals is a basic tool having extensive application in digital signal processing. 5.9 In general, the problem is to correctly compute signal values at arbitrary continuous times from a set of discrete-time samples of the signal amplitude. In other words, we must be able to interpolate the signal …
