does anyone know of a filter design that can smoothly be changed from
LP to BP to HP with a parameter? IIRC LP/AP/HP could be done simply by
perfect reconstruction LP/HP filter pairs, but never seen something
similar for BP in the middle...
The filter doesn't need to be "perfect", it's for something
musical/creative rather than a purely scientific goal...
This may sound naive, but would it not be possible to chain an LP and a
HP filter in series and adjust their dry/wet rates according to
parameter?
it's not naive (but it's parallel, not chained in series) and at one
time in the distant past, we called that the "Tone" control.
