about optimizations: like Anders Torger notes in his docs to brutefir:

http://www.ludd.luth.se/~torger/brutefir.html#bruteconv_4

the cycle burner is the complex multiplication. So if anyone has SIMD
assembler routines for complex multiplication of two float buffers
(fftwf_complex *) in his cupboard, please bring it out :)

jack_convolve uses complex data format, not half-complex like brutefir.
so i suppose i can't simply rip his code ;)
