Important questiong about real Input Voltage

Post by Ilya-v » Tue Apr 11, 2017 11:57 am

Hi.

This is an important technical question for the folks that know how the heart of ReValver ticks.
The result of knowing the answer will yield a more realistic response from the simulated amplifiers.

What dbFS in DAW the amplifier simulator treats as 1VAC Peak (2VPP)?
Most VST Amp Simulators treat 0.0dbFS as 1VAC Peak in the digital world at
the grid of the first tube stage, is it the same with your amp simulations?
The reason for that is I calibrate my audio interface with a function
generator with a 1VAC at input and boost in DAW till it reaches 0.0dbFS, the
result is the simulated amp will behave like the real amp, yet I still have the full
headroom of my audio interface.

A real world voltage has to translate to the simulated digital world right?
1V should be 1V on a real tube or simulated tube.
The simulated tube should receive a guitar voltage at the input, so my goal is to know exactly how the you software treats 0.0dbFS signal.
Most guitar plugins will treat 0.0dbFS as 1VAC Peak, is this the case?

Thank you.

Good question! I'd like to learn more about this!

I wonder if the support team even visits this part of the forum?

This is really crucial information to achieve maximum realism from the simulated amplifiers.
Without proper calibration I can set my Telecaster to be as hot as an EMG Guitar... this can't happen in reality without a booster. :lol:
1V is 1V, there should definitely be a dbFS value that the simulation treats as 1V.
