Not sure why you get those results.
I still get -90dB THD+N
samplerate: Automatic (set by virtual loopback to 48000)
pitchquality: 4
scratchquality: 30
autogain: off
generated wav file: 16-bit 44.1khz 0dbFS 1000Hz sine, no dithering

Hi Addion,
I've found de problem :
The default value on VDJ mac version of :
ScratchFilterQuality (and not ScratchQuality)
Was at 8 (to low ) and i've to change it at 30 ?
With 8 quality of SRC doesn"t work..... a lot of user use 48000 samplerats... by default you should set SRC settings at Pitch 4 and Scratch to 30 (Pitch 2 and scratchquality at 8 give -40/ -50 THD + N with 44100 files to 48000)
Even with Pitch 4 and Sq at 30, only 91 THD-N with other app reach 97 and 129 with 24 bits files...
please set by default higher quality SRC standard without the need to hack option wioth two settings....
The default settings give -40 -50 THD+N for user that use 48000 samplerates with a lot of controller midi audio that are fixes at 48000.. it's not enough.
And change the engine read/file file to 24 bits , the VDJ internal engine is 32 bits.....

Checked on mac too
Can you check the tool tip of the gain slider to make sure it's not adding any gain?
Edit: and you checked scratchQuality setting as well?

i've answered : see edited post before within you answered me:)
The default SRC quality settings are to low (2 and 8) and far from competitors.
When we install VDJ, the. default should be (Pitch 4 and Scratchfilterquality 30 )
It's the actual standard of SRC THD+N of other music player and DJ software
have a nice day
