LeastSquaresFilterKernel

LeastSquaresFilterKernel[{{ω1,…,ωk-1},{a1,…,ak}},n] creates a k-band finite impulse response (FIR) filter kernel of length n designed using a least squares method, given the specified frequencies ωi and amplitudes ai.

LeastSquaresFilterKernel[{"type",spec},n] uses the full filter specification {"type",spec}.
