be enough, depending on the application.

us the Linkwitz-Riley type. Outputs add to a perfectly flat
frequency response, but the phase response of the recombined
signal is not linear. It won't matter in most cases.
For ready-to-use L-R filters, get zita-lrx1. It provides up to
four bands using 4th order filters (i.e. 24 dB/oct).
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
