Crossfader with "constant power" isn't --- pic to prove it

So you want a crossfader which will level out your transitions for you? Isn't the whole challenge of a good transition to be able to blend the frequencies seamlessly between two tracks?

among my people, we call it "input gain"

umgawa!

Tracks that are phase coherent, add when using constant power.

Right-clicking the crossfader lets you choose from seven fade shapes.
Live 6 added the ability to choose from a number of different crossfade shapes by right-clicking on the crossfader. These change the attenuation characteristics of the fader across its travel, and in turn affect how the two audio mixes are blended together. The key characteristics are how fast a signal fades in as you move the crossfader, what the combined level of 'A' and 'B' is at the centre position, and whether a signal hits full level before you reach the end of the fader travel. The diagram to the right shows the approximate fade shapes (as far as I can tell) for the different settings.

I don't think you're correct though. The X-axis of a waveform is amplitude, not power, that much is true.

What does that mean ?

If you fade between two different white noise channels, the transition is essentially seamless as required.

The bump in the middle of constant power fades is definitely to do with phase relationships between channels, because 2 white noise channels would have negligible summation/subtraction, and demonstratively fade perfectly with constant power.

Case closed in my book at least.

edit: Also, think about it, how could you make a simple curve that adjusts according to what is fed through it? Of course there's going to be large variences between the amount of phase addition/subtraction that takes place between all sorts of different sources.
