For a 2048 tap coefficient file this results in: 48000 / 2048 = 23.4 Hz. If high resolution results are required, and high latency can be tolerated (e.g. - audio playback only), then a high tap count is viable.

"WebOct 23, 2024 · For an FIR filter, for a given cutoff frequency, the slope of the impulse response plot ( H(f) vs f) is steeper for a higher order filter. So, to achieve higher attenuation for the undesired frequency range, you increase the filter order. But what happens when the filter order is so high that the impulse response is an ideal box function? " - Convert wav to fir filter
