const float & q ()Quality factor, usually denoted as "Q".
Indicates how narrow the frequency transition is. Higher Q values imply narrower
notches/peaks and steeper cuts/shelves. Must be positive.
Optional.
If used in `SetElementState` and represents a change in this band's q, then `CAN_CONTROL_Q`
must be set in `Element.supported_controls`. Must be finite.

const bool & enabled ()Enable/disable the band.
If disabled, audio still flows through the equalizer but this band has no effect.
If absent in the return value from `WatchElementState`, the band is enabled.
If omitted in a `SetElementState` call, the band's enable/disable state is unchanged.
Bypassing the entire enclosing processing element (by setting `ElementState.bypassed` to
true) does not change this field's value, although for an equalizer band to be functional,
its enclosing equalizer processing element must be both started and not bypassed.
Optional.
