Hum it doesn't look good :/

PASS Initial latency of convolver is silent.
PASS Triangular portion of convolution is correct.
FAIL First part of tail of convolution is not sufficiently small: -129.7413645172823 dB
FAIL Test signal was not correctly convolved.
PASS successfullyParsed is true

One question, do I need to apply a function window to the timed data before performing the FFT?
