reduce required SNR to accept KissFFT ConvolverNode implementation

as used in Firefox on some platforms.

minRequiredSNR = 83 permits the quadratic mean of errors to be up to
(10^8.3)^-0.5 ≅ 0.036 * 16384 * 2^-23, implying that most of the samples would
have error significantly less than one ULP for the representation of the peak
of the ramp (16384).
