As long as the speaker is moving.......would be the closest you're ever going to get to simulating it...

That's being a bit pedantic. The effect would still be similar.

The sound is moving to you from a stationary speaker.

And then it moves to you from another stationary speaker.

and then again from another speaker.

The sound source is never........ ever........moving towards or away from you.

Never, in this video , do the sound waves get shortened or lengthened (raised and lowered in pitch) from the movement of the sound source. There is no movement of the sound source. There is no doppler effect.

So your position is that since the sound is not being conveyed on the car's chassis, but rather by timed speakers, the result would be different? When you say "sound waves", why are you assuming more than one? The sound of the car would only be a single complex sound wave. After all, a 105-piece orchestra only produces one. Isn't the sound wave shortened and lengthened by the physical distance from the listener? (Throw a pebble into a pond.)

One of the problems I see is that we (or at least I) do not know the methodology that is used in the project. Did they record the sound of the car with an onboard recorder? If so, wouldn't this be a single waveform? Is the playback system utilizing a delay to each speaker in sync with the light? If this were the case, would the system then not become a giant 3D (albeit low res) sampler? Why does the source need wheels? I'll bet you have stood onstage in a large outdoor venue where the distant speaker towers were delayed. Did the sound appear to move away from you? How about if there were another tower beyond that with a longer delay?

If they recorded the sound of a car's lap using a microphone at each speaker location and played back all tracks at once, would the result be different? I originally took the meter bridge in one of the b-roll shots to be gratuitous, but maybe this is what they did.

What I am trying to say is that, without empirical evidence, or at least something more scientifically concrete than mere gainsay, I am skeptical. After all, this is not a naturally occurring event, so how can we know with absolute certainty? I can't say you are wrong, I'm just curious.

This has all become too much typing for me, so, I am in Tampa and would love to buy any/all you guys drinks or coffee if you'd like to come down and discuss this some more, but for now, I'm out!

Think about it, man. Does the pitch of a symphony orchestra sound -sharper- for the people who are sitting -closer to it? Not bloody likely! Do the people sitting farther from the speakers at a concert hear a lower pitch?

I I hardly think so. Maybe if they were riding by in a speeding car. :).

The you tube onboard I posted in reply # 33 is the recording Honda used for the recreation I posted in reply #1.
If the you-tube contains doppler effect, by recreating a recording of doppler, wouldn't the play-back duplicate the effect?

I just found this, late to the game.

Maybe it is the sleep depravation, but I found it incredibly moving.

Doppler or not.

that's all the thread was meant to be :)
