Filterbank
Like a Synthesizer Filter set. Most Filterbanks are fixed filter banks with a number of BPF plus HPF and LPF at the top/bottom end.
Filterboxes are often analog. Some contain envelopes or/and LFOs but a Filterbank does only contain the Bands and sometimes individual outputs for each filter, a filterbank is an important part of a Vocoder
