Are you doing something quantum mechanically? Or are you just fond of the word quantum? ;-)
Yes - part of the auto-focus circuitry that tracks sound objects (as a very small signal)
I had to create a device that was dead quiet and begins tracking at 0.07 nano volts. The quantum reference thread used to detect velocity has an extremely high Z. (90+ gig). The velocity control system is driven directly from this process which squeezes the signal [gauge] into a virtual plasma. The plasma is also high Z. The thread is then combined with the signal at the plasma level to ensure impedance matching.The signal is suspended this way so the auto focus circuitry can fully dominate the signal velocity while preventing it from "touching" the surrounding template and support circuitry. This keeps contamination out of the signal.
The velocity control system is a twin running shift generator (red shift - blue shift) which is held to a servo neutral point under tremendous pressure.
Once detected, extremely tiny amounts of signal velocity are met with a counter measure (injected into the plasma) of greater than 700 db in real time.
All of this is held in a solid substrate made at the factory.
The signal velocity has no chance of deviating away from a dead accurate
Max error would be in nano degrees of phase shift away from the fundamental.
It is impossible to generate harmonic distortion.
This technique is used through the entire chain.
The output is a virtual clone of the input (only bigger).
Since the output velocity = the input velocity it will pass the electrical version of a sound wave all the way through at exactly Mach One.
The hardware itself which has no sound of its own emulates the properties of air. Both pressure and time are locked in sync with the music signal.
The experience can be described as listening through a large hole in the wall to a performance happening in the next room. Nothing but air.
That's live.
