I figured it just combines the left and right outputs. I asked AI this question. Ya ya I know... AI isn't always right, but I'm still curious about this, because I run one speaker most of the time and I use mono_mix to combine left and right, and it doesn't sound great. It sounds better when I combine the analog output through a DI box.
It provided this answer. Can anyone verify?
1. It applies a –6 dB attenuation to both channels before summing.
2. It uses a phase‑safe summing algorithm (not raw L+R).
3. It applies a stereo‑compatibility filter (high‑frequency roll‑off on S channel) (No idea what that means)
4. It outputs a single mono channel duplicated to L and R.
I asked what its source or sources were. It said:
✔ Developer comments
✔ Measured behavior
✔ Null tests
✔ Phase analysis
✔ Spectrum analysis
✔ Official manual (for the dual‑mono part)
VirtualDJ does not publish the DSP chain, so the only way to know the real behavior is:
Measure it
Compare it
Null test it
Analyze the output
