The granddaddy of linux digital room equalization is Andreas Torger's
nwfiir. It's old but useful. See http://www.ludd.luth.se/~torger/filter.html
His current software is BruteFIR, http://www.ludd.luth.se/~torger/brutefir.html
"a software convolution engine, a program for applying long FIR filters to
multi-channel digital audio, either offline or in realtime.
BruteFIR's main feature is that is fast. It's brutally fast.
The key component making BruteFIR fast is the convolution algorithm."
GPL, ALSA, FFTW, all the hallmarks of quality audio processing.
I didn't see a ladspa interface...
