coming or going

I'm in search of an FX ensemble that incorporates, simultaes or replicates the dopper effect. I did a search with the keyword "doppler" in the user lib. No luck. Any suggestions?

 

simulates ... ugh fat fingers!

 

learn how to do it yourself instead of egging everyone else on like on your earlier posts..........heh!heh!..... Doh!!!! spend 1 yr on reakotoro! and then post - doh!!!!
heh!heh!

yes I am in a wise -ass mood - sorry! Don!

 

OK, I suppose I had that comment coming at some point. Although, in all fairness, I must say I do contribute. Check the Absynth User Lib! That's about the level my programming ability. I bearly have time for composing and learning the dozens of non-Reaktor synths I have.

Besides, I was just asking if something existed, not asking anyone to build one ... unless you're so inclinded of course

why don't you just use a filter and a pan to do it ? ;-)
you may achieve exactly the same result !

That's funny! If I had any idea what that meant ...

 

I don'y understand how you guys are smart enough to know how to take a math formula and turn it into a musical instrument, but still don't understand I was simply asking if anyone knew of a Reaktor ensemble that used the principal of the doppler effect, maybe under some other name?? This is the Reaktor forum, right? Not the Reaktor Programmer Only forum, right? Not everyone who makes music with Reaktor is a math whiz.




....whatever

 

you are a registered user since sept 2002? Perhaps another link:

First, google Spacestation VST. This is shareware plugin that does doppler shifts. It would give you a paradigm for what you might do in Reaktor, and will let you listen and see what can be done. AudioMulch I think also has a dopplering thing in the SSpat module... and that reminded me that there is an ensemble called SSpat in the library that looks like it does dopplering, so probably the rest of this which I wrote before this sentence is useless....

If I were doing it I would start with the following model.

Use an XY to represent the position of the sound and the position of the listener. The listener is the cursor, and the sound is the dot that is changed by the X1, X2 inputs. I would drive the listener by some sort of oscilator, say an LFO, say to make the sound ping pong back and forth on the X axis. Keeping track of the direction of travel of the sound (prob. using the differentiator filter?) I would set up a test to see if the sound has passed the listener, because that is when doppler kicks in, and calculate this distance as DeltaPast.

All of that would be in one macro, call it mover. Mover sends two outputs to sounder: Position, DeltaPast, and Freq (of the LFO). Sounder uses Position and DeltaPast to position the sound and shift it. I would use a GrainCloudDelay in Sounder: boil input down to mono, use Position (suitably scaled) to drive the Pan input of GCD, and use DeltaPast to drive the P input. This is where you'd need to look at the math because the shift is related to the velocity of the sound, which will be input to sounder as Freq (the higher the frequency, the higher the velocity). So you need to do some math here--but note that unless you need to be accurately simulating, your math doesn't need to be bang on. You need something that sounds like a doppler shift and sometimes with effects and so on you want to exaggerate, or let the user play with parameters that go beyond the physical.

 

Yes, Spacestation appears to be the exact thing to do the job. Windows only, unfortunately for us Mac users. Thanks for the suggestion.

 

Rameau ---- thank you for some interesting thoughts on the XY graph thing....I just decided at about 3:30 A.M. today to start a new ensemble using this XY graph/grid control thing.... After seeing a number of ensembles using this module or aspect - it seemed appropriate for my new ensemble idea....Thanks so much...

Don - sorry for the bust butt yesterday

couldn't resist being easter with all of the eggs! you know.....

 

GRM Tools (VST plugin suite) also has a Doppler module and I think this is mac and windows. Excellent set of tools--but pricey.

 

Hi,

I've managed to get some usable Doppler effect stuff using Ben Suthers' "Spacial Tool"...The SSpat thingy works too, and I think there's also something made by Joe Orgren, tho' if my memory serves me right this might be a Reaktor3 .ens.

As I recall all the above need a bit of fiddling & tweaking but will give pretty believable results.
