Hm...

Analog Mixing = DA conversion from computer to analog mixing console back to computer via AD conversion

Question: Are your converters higher quality than the 64-bit summing engine of Live 7 (or any 32-bit summing engine)?

What have the converters got to do with 64/32bit summing engine?

Is that not a different thing?

Sure converters and summing-engine are a different thing. But when you think about mixing analog "for better quality" you have to consider that you might lose more quality by going two times trough converters (DA-AD) just to be able to use an analog mixer. The quality-loss from the conversion process might/will likely be higher than the quality gain by using analog mixing over digital 32/64-bit mixing. Not to mention that you need to use a high quality analog mixer with noiseless gainstages and faders for summing.

but exactly noise is so beautiful in sound.

I see, but would it really be that much? I think the point of doing it that way is that there is more room in the mix, it is supposed to sound less compressed going through an external mixer. So really its weighing up the benifits of a better sounding mix (+ or - added analog harmonics) versus a loss in sound quality. Allot of producers do it this way even if they use all vsti's will still mix externally.

Ah, well ok, you mean analog noise of the mixing console to add life and warmth. But converters ain't exactly analog, so watch out that they don't diminish your analog noise upon AD conversion and they they don't add louder quantization noise upon DA conversion.

No i mean add space, the fact that it adds warmth is just another benefit but you can obviously get that through other means.

Yes, it sounds like a different mix to me too. The background guitar is louder in the computer mix?

Erm, guys, you're not talking analog vs digital here, but colored sound of mix A versus colored sound of mix B. Whereas the analog mix may additionally be coloured by the conversion unit. Not to mention that the audio quality of this video is sub par. Sure its nice to get the color of that external analog mixer if you like and want this color. But most likely you could also get that with some EQing or other effects (in that regard the external analog summing bus is like an external effects unit). Besides the analog mix places the guitar alot more into the center whereas the digital mix has the guitar paned to the sides (actually it sounds a bit as if only the stereo effect of the guitar is heard). But can that be contributed to analog vs. digital?

There surely are audible differences between digital and analog summing. Digidesign has published some quality audio examples on their site where you can listen for yourself if you can hear differences between their 48-bit fixed-point digital mixing-engine and the analog mixer. I do hear differences, but they are very subtle and not that blunt into your face like in this video comparison.

Don't fall for that, it's a scam! You can save tons of money by purchasing one of my patented FM receiving units that will literally catch free unlimited noise from the ether!
