It's not unusual to use hundreds of taps for a clean linear phase filter with a sharp slope. Discrete convolution reverb would need hundreds of thousands - which is why you use an FFT for that.
interesting. just looked at a datasheet for a modern audio dsp and they set aside memory for ~256 coefficients per 48k channel. i guess big filters are a thing.
still, you're looking at applying a window before the fft in most applications. that's a full pointwise multiply before even stepping into the fft (and back).
reverbs have delay lines, right? what does that look like in the spectral domain? some shift of the phases?
