Hi all,

I'm trying to understand how the "room tone" works in VE PRO 7. A track has created by VE, but no signal is visible at all. Only if I drive the "Room Tone" volume to max in MIR PRO, I get something of a signal of less than -60, which is nowhere even near audible.

Any idea if I might be doing something wrong? I enabled a secondary microphone just in case, but that didn't seem to work either. Is the signal supposed to be this low?

Thanks!

Welcome iPiano,

Default levels between -65 and -70 dBfs are indeed something you should expect to see and hear.

The natural levels of RoomTones differ, of course. In reality, a high-end studio location like the Synchron Stage Vienna will exhibit much less noise-floor than an exposed, hardly isolated building like a church. RoomTone levels also depend on the chosen Main and Secondary Mic position to some extent, and on the number of (virtual) microphone capsules. 

... but as MIR has no idea what the levels of your instruments and other signal sources will be in relation, it's completely up to you how much of this "natural dithering" you bring in into your mix. A good rule-of-thumb is: MIR's RoomTone should be just loud enough to cover the end of a single reverb tail behind a soft "pillow" of uncorrelated noise. :-)

Thank you very much for your input! It works indeed as expected. I didn't realize it is the room noise. The word "tone" got me on the wrong foot.

I see - this can be misleading. :-)

In my defence: I didn't make up this labelling. "Room Tone" is indeed a commonly used trade jargon term for the natural noise floor in a room (and a recording thereof).
