DEQX vs Twindac+/Django (Off Topic)

Hi Peter,

That was digital-in and digital-out.
Note though, it was the parametric equalizer (and feedback destroyer), but
the principles are the same; without changeing anything (so no frequencies
changed) the sound was already flat. But *also* note there was already a
standard -9 dB or so attenuation applied, in order to have headroom for
allowed gain, whether I used that or not.

The analogue version of the Behringer worked better for retaining the
sound (details), but it is noisy (not audible, but by measuring) and had a
20ms (processing) delay.

Interesting. Where you feeding a 16bit signal to the DEQ?
I think it upsamples everything to 24bit. So -9db should be 22 bit at worst. If it does not upsample you were hearing 14bits which would easily explain the flatness. If it does upsample and you prefer the analogue version, the upsampling algorithm or jitter seem the likely culprits rather than the digital processing part.

Best
Giulio
