> Hi to all,

Hi all, i think that the reason why different DAWs may sounds in a little
different ways, is because of the so called "Pan Law", before than the
summing algorithms.
A mono sound, middle panned, is 3dB more powerful than the same sound panned
all L or R.
For a stereo sound the gap is 6dB.
Different DAWs face that "issue" in different ways: i don't know it
personally but i found on the web that Pro Tools HD give a -4.5 dB to the
sound in center, Cubase SX has -3dB by default but let you choose if -3,
-4.5, -6 or 0dB, etc...
I don't know the Ardour behaviour now, but i think it's equal power (without
decreases in the centre).
Those differences in panning may influence a little bit the "sound" of a
DAW, especially if you are mixing sounds panned close to the centre.

Hi to all, I'm an audio engineer in my day (an=
d night) work, but definitely not a programmer. Yet there is one endles=
s discussion between friends and colleges of mine that I usually do not par=
ticipate in due to the lack of knowledge.

The topic is algorithms of software (DAW) mixers. Some people say that they=
can hear a sound difference between several kinds of software mixers (e.g.=
Cubase, Protools etc.).I must say that I never made any serious A\B te=
sting but I didn't notice that there is any difference. Although I do w=
ork with Pro-tools and Cubase (in other studios), most of the time I'm =
actually using Ardour (and I'm loving it).

My questions would be:1. Is it only me that can't here a differ=
ence between different DAWs mixing algorithms?<=

2. To the developers out there, what is your opinion? Is t=
here a better/worse algorithm, or is the whole thing another "pay 600$=
for this software - it has great algorithms!!!" hype?
3. If there is a difference what's the explanation?4. Analog emulat=
ion plugins. How does one "emulate" analog waveforms in a digital=
world? That sounds like a paradox to me.Hope that's not to man=
y questions in one mail.

Thanks for your timeMoshe
