One of the few node types I've been sorely missing, that could be implemented
in JS but with needless latency, is a noise gate/expander node.

Would need standard noise gate controls: threshold, attack, release, hold, and
possibly an attenuation setting, maybe even hysteresis control.  Additionally,
an AudioNode output of the attenuation would be very helpful for doing
sidechain gating.
