Software for Linear-Phase Filter Design

The Matlab Signal Processing Toolbox covers many applications with the following functions:

All of these functions except firls are implemented in the free, open-source, Octave Forge collection as well.

Methods for FIR filter design are discussed in the fourth book of the music signal processing series [86], and classic references include [64,68]. There is also quite a large research literature on this subject.
