rdfs:comment """
Four adjustable biquad filters in series, in a vector arithmetic implementation. The default setup is an identity filter with a mode configuration of lowshelve, band, band, hishelve, all at zero gain.

The Q control value maps non-linearly to actual filter Q: a zero control value results in filter Q of ½, a value of 0.3 corresponds to a Butterworth-equivalent Q of ½√2, and the maximum control setting of 1 results in a filter Q of 50.

Parallelisation of the serial filter topology causes its response to lag by three samples.

Control response is smoothened by crossfading between two filter banks.
