There was a thread on Gearslutz about it, but I can't find it now. Some guy noticed a lot of aliasing from the EQ, which obviously shouldn't happen in an EQ since it's not adding harmonics like a compressor etc. In the end, they worked out the aliasing is caused by truncation noise.

They guessed Apple kept it like this for legacy reasons; lots of people have projects that would sound different if they changed it.

Just FYI... Keeping your mixer faders at unity doesn't mean you aren't hitting the red between your components. Example...

Instrument -> +3db -> Insert -> -3db -> Mixer reads -3db and you think all is well.

Maybe you should put a level meter between every single component in your project. That way you can be 100% sure you aren't going into the red.

i still dont think im doing anything wrong really, perhaps i would agree with Rann if i was working with hardware to keep the instruments dynamic range into the mixer to get better noisefloor etc. but in a software mannor i cannot for the hell of my life understand that what im doing is wrong. i tried raising all the instruments by +15dB and lower all the mixer channels with equal -15dB. not a tiny bit of change on the master, nor the individual meters. i think this is bullshit. i bet all values are calculated at reals (aka floating point) and therefore not matter at all.



I'm not sure in the digital domain what happens, I will ask this to my old Audio teacher, but in the analog domain the instrument gain stage should affect the "timbre" and/or "character" of the instrument as we use to say here in my country "signal gets hotter".
Maybe you can try a simple test using a good spectrum analizer with a high FFT and sending a simple sine at let's say 1Khz with gain at zero and fader at zero (nominal states) and then change volumes first in the gain and then in the fader, take some screen captures and compare if the sound gets distorted or altered in some way. I can try to do this test but I'm not in the studio right now.

by the way what bit resoulution and sample rate are you working?

truncation is different with 32 bit float but i mean it is something you are never going to hear or notice unless somoeone tells you it does and you start imaging shit like those people that buy really expensive cables to run a connection 1 metre.

Here's the thing; Reason (as most DAW's are) is 32bit floating point, except at the output stage which is 24bit becuase for the physical output it has to be 24 per your dac.

So in practical use it is impossible to clip 32BFLP between faders or gain stages so long as you don't clip the master.

Now in theory, lowering one fader or gain stage by x and then raising another by that same amount x should result in the same thing, but here's where it gets complex;

Many VST/AU/instruments/effects do different things in terms of dynamics and even sound different depending on the volume or how hot the signal is. In this respect, working the way you do is not how they were designed to be used so you may get unintentional results or not the full performance from the device in question.

The only way to be sure is to do a null test - record a sound from an instrument the way you currently do it (adjust gain on the instrument then have the channel fader at 0) then the normal way of gain staging (have the instrument at unity and set the fader to match the previous master level output).

Bounce both to audio in the same way, import them both in to a fresh project, one on each track, invert the phase on one and you should have silence.

If not, then you know there's a problem.
