JESUS WEPT. We've been through this. Summing in one DAW is exactly the same as summing in another, give or take some dithering noise. Ableton's sound engine does not have a "sound". Neither does Logic's, Cubase's or Fruity Loops'. This is like goddamn Spinal Tap. I bet if you could turn Ableton's master bus up to 11 without the output clipping then everyone would say it sounded fucking great.
Despite all the rumors, there have been a lot of experiments that showed that Logic, Cubase, Live etc... all sound exactly the same, as long as we are talking about digital summing, which is the main contribution of the DAW. The FX are obviously different, but tbh i just dont get what Villalobos meant there. I mean Ive heard a lot of tracks and recognized the Beat Repeat FX or the Filter Delay from Live, but i seriously doubt that anyone can recognize a track by the sound of the DAW. You may be able to tell by the way the track is programmed or which synths are used, but thats a byproduct of the setup and the workflow of the DAW, not the sound engine.
This is exactly it. You CAN in many cases spot an Ableton track a mile off, but not because of Ableton's supposedly inferior audio engine. It's because of three things:
1) Ableton's effects and library samples
2) Ableton's workflow (eg session view, the ease with which clips can be divided and duplicated along bar lines)
3) The strong correlation between Ableton users and talentless hacks making shitty minimal and deep house
...although I'm really struggling to make things sound really clear with the EQ8. Still need to check how the Hi-Quality mode makes a difference though.
AFAIK, the "Hi Quality" mode of an effect in Live 8 simply upsamples by 2x then downsamples on the way out. In the case of EQ8 this has the effect of straightening out the frequency response at high frequencies (where digital EQs can have trouble). You can see it on the graph if you switch to Hi-Quality and back with, say, a LPF at 10kHz.
