Topic: Raw output sound
Currently, VirtualDJ seems to apply a limiter on the master output that is not available or adjustable in the options. This can be observed graphically by comparing waveforms (wave subtraction tests).

Test conditions:
Same track, original BPM, original key, same output level. Compared between:

Windows Media Player

VirtualDJ

Serato

Rekordbox

When listening carefully (even blind testing), it is relatively easy to distinguish VirtualDJ. The sound seems to have slightly less detail, as if it is being affected by a limiter somewhere in the DSP chain.

In my opinion, this limiting effect could be improved by allowing more headroom (e.g., -6 dB or -9 dB) and applying gain compensation afterward.

Today, the only aspect that puts VirtualDJ behind Serato and Rekordbox, in my view, is the output sound quality. That’s unfortunate, because otherwise the software is excellent.

Feature request:
I would like to have control over this “limiter effect” (or whatever processing is being applied) in the settings. Ideally, when playing a track at original BPM and original key, the output should be indistinguishable from a neutral player such as Windows Media Player.

Thank you for your consideration.

Try the "zerodb" setting
 
I'm actually talking about zero DB setting - sorry to tell you that you seem not having the skills to understand what im talking about. This is not a 1 level support question. Its an dsp architecture issue to resolve.
Please raise this issue to engineers - maybe CTO.
 
Sorry for trying to help!

I would like to call you out on that, as I have done a lot of blind tests to a lot of DJ's and other "sound experts" without being able to tell anything apart, except for Traktor that compresses the sound

Then you don't understand the difference between a limiter and a compressor

It has been discussed over and over again, and it won't happen.

If you turn off autogain, then it will be.

Autogain MAY or MAY NOT rise the volume of a track slightly in order to achieve similar audio levels among all tracks. This means that some tracks may hit the limiter.
You can escape the limiter either by turning off auto-gain (but then when you apply gain manually you will end up in the same situation) or by using the zerodb setting (HEADROOM) to lower all the tracks all together.

Since you seem arrogant enough to even try to understand what we're trying to say, I will just say this:

VirtualDJ has a brickwall limiter that engages when the outgoing signal is going to shoot over 0dbfs.
It's not a compressor.

If you think that we are not skilled enough to understand, then you should perfectly understand now why it won't get removed, nor it can be controlled.
