gain staging using neb in reaper

Postby xyxxjx » Wed Nov 07, 2012 5:51 am

I want to set my system up calibrated @ -18db using nebula in reaper, can someone tell me how to go about that or maybe point to a good guide.

Insert good VU meter plugin (set it up 18dbFS = 0dbVU) before Nebula and adapt your signal - VU meter should be jumping around 0db.

Then, put VU meter between Nebula instances and check levels. Remember different programs (libraries) often require different input levels.

Alternatively, you can use NebulaMan to render your files with peak-rms normalization to -18db.

A good starting point :)

this is the plugin for you!

http://www.kvraudio.com/product/stereoc ... me-records

there are 32/64 bit versions and its totally free :D

only use the stereo version, its set to default to 18dbFS = 0dbVU

just make it the first insert on your channel and adjust the big volume knob on the right until the needle is averaging around 0 on the dB meter... job done!

how about adjusting the input level of nebula to get the vu's around 0db? would that work?

@zab, you mean the meter should peak around 0dbvu? @dav Thanks for the meter. I would also be interested to know about nebulas input volume, I often find myself turning it way up.

The biggest issue you can have by turning up the level high with the Nebula input is that this is like sending a hotter signal into the input of a piece of hardware. It will drive the device harder, which CAN be cool, but not always wise. The input control on Nebula is not just a transparent level, it is setting how high or low your audio is hitting the input of whatever hardware the preset is emulating.

Yes. More you go over 0dbVU, more you are driving input - what happens then depends on a used Nebula program. Sometimes sound come 'alive', sometimes clipping may occur.

In Reaper you could use the SWS function "SWS: Normalize item(s) to peak RMS", the level could be set through the function "SWS: Set RMS analysis/normalize options".
Of course is less accurate than setting levels track by track with a VU meter plugin, but a very nice shortcut: in a single step you can select all tracks and apply the normalization directly on items.

@Vern Does normalizing degrade the audio in anyway?

How high should the leds peak on neb input in general?
