Auto-Gain not working properly

Postby Picaso on 22 Mar 2016, 19:19

Hi folks,

yesterday I tried Cross at a party. Unfortunately the Track Gain's were really different from each other, so a lot of songs were louder than expected... I mostly play Salsa music!

I read about a known issue of auto-gain if there is too much silence in the track. Is this going to be fixed? Because to me setting the track gain of 2000 songs is not an option! :/

I had VirtualDJ before and it worked quite well...
Thanks,
Pablo

I've seen problems only with files with significant parts of silence (a two-part song with a gap in the middle or a bad vinyl rip with lots of extra silence in the end). It is pretty rare though and my library contains many different genres. Salsa music shouldn't cause problems (unless there are lots of vinyl rips...)

Well, in Puertorican/Nuyorican Salsa there are a lot of breaks in the music usually followed by a half beat of silence... There are a lot of old bad quality recordings too which people still love to hear because of the energy of that era. Maybe these two could cause the problem?

In general I felt really insecure about the whole sound quality/loudness yesterday :/ Maybe it was also because I was using a Split-Cable and not an controller/second interface!?

That may be related.
In the collection grid you can make the Gain field visible by right clicking on the fieldnames in the header.

Your problem tracks likely have + or - 12.

At the right field width you see both the fill option as the knob fader. If you dblclk the fader it will set to 0. This may be your quick and dirty fix.

Just maybe you can batch select tracks and set the gain via the info menu. I have never used this for the gain and am not at a PC now to check it out.

If you have to do manually you can do many tracks in appx 15 minutes.

If you first add them to a temp playlist (sort on gain, select top, scroll down Shift select bottom) you work through quickest. Have the playlist sort on nr and not on gain.

A half/whole beat gap would not cause wrong gain setting, the silence needs to be longer so maybe the issue lies somewhere else... also perhaps some tracks have been mastered+mixed differently (too much or too little bass, for example which causes unreliable auto gain results).

There's an easier way of finding problematic files by making a Smart list search, for example something like

"Gain is less than - 6 dB" which will then list those that fill the criteria. Experiment with different settings and see which tracks are listed.

After checking out today with my new Denon MC 4000 it seemed to be okay... I also checked the gain values and none of them are bigger than 6 ... I will try it next week at another party and see how it goes. Maybe it was due to the audio quality of the split cable and split mono ...

Ah by the way if I import my old VDJ Library, are Gain-Values also read by Cross?

I don't know if the gain values will transfer. However, assuming that they do not.

You can bulk select tracks in the collection

right click
hover over to analyze
right click again
you will see the option for gain only.

This will analyze the gain for all the selected tracks without changing any beatgrids, cue points or loops
