WIND SIMULATION (Doppler effect+phaser+Wah+Leslie?)

[richon]

When you're at the beach, a little far away from music speakers playing "happy beach songs" in a windy day, you hear (as the wind blows) a change in Pitch and Volume of the songs being played, right?

I want to reproduce this.

Maybe a random variable LFO or something else to make the sound of the guitar disappear or be to present (like a Wah effect) and then far away....   Like a Horn rotating very slow in a windy day.


So far I know the Frecuency should vary just a little bit up and down as the Wind blows... and also change the EQ as it spins

Leslie are somehow to fast?
Phase is really phase only, or should a Phase effect out of phase be added to the Original sound?

please share your thoughts

I don't know about all this, but I do do this thing with my wah and delay.

I have (or had, the thing is fried now) a setting on my DD-20 for long delay and a lot of feedback, and what I would do was take my volume on my guitar all the way down, put my overdrive on and then click the wah on and rock it in such a way that it sounded like a howling wind storm. VERY cool for ambient stuff.

thanks for sharing, but I was aiming at another effect

to listen the guitar normally and then it start to fade in a change of EQ sound (like a guitar going away, but no reverb) , not very clear...

like a very slowly spinning HORN that's playing a guitar solo.

I was leaving that one for you, Mark.

If what you want has to include the fading out of the guitar as (presumably) the wind blows the sound the other way, you could add to the wind simulator a signal loss circuit which faded the guitar up and down, similar to the pseudorandom  stuff going on in the wind simulator. A P-channel JFET to ground fed a semi-random signal on its base and set up to cut the guitar level might do this well. There's lots of room to tinker with this.

So , you say, I could use a RANDOM LFO to simulate how the wind blows (EXCELLENT!)

then, maybe, with the same LFO control a Volume or Tremolo to change the Volume of the Guitar, as the wind changes (EXCELLENT AGAIN)

and Then ...  could this same LFO control a way to change the SOUND of the guitar or to mix a clean sound with a EQed sound, so it changes  "aparently" the way the guitar sound completly?

Thanks all for sharing with my CRAZY idea

PS: Yesterday I heard some HENDRIX solos doing this, but I know this is with mixing techniques at the studio. Damn, Hendrix did it before like 40 years ago

Many sound effects accompanied fuzz-wah pedals in the 1960's.  Wind and/or siren were typical.  So the pedal would have a 4-position switch for fuzz, wah, siren, wind, or perhaps wah/siren/tuner.

[richon]

As I looked for info on :

RANDOM LFO (maybe using 40106)
Noise generators
Old Fuzz-wah-siren-tornado effect sounds
tremolos
phasers
wahs

then I saw this: http://www.youtube.com/watch?v=T9wuwv7j-KE&feature=related

Yes, it is a TORNADO SIREN

this is the way i want the sound to change.... 

so, it seems that I want not a random LFO but a simple LFO that regulates how the sound changed from original

like a strange variable Clean+Wah sound...  that makes the Wah oscilates very slowly over a clean sound....

did you get me this time?

Also have a look at "Panning for Fun" at GEO for how to do the crossfade.

a konch?.........or 2..stereo...


sounded good when i was a kid at the beach.........

the WIND sounds great, but I want the sound to change, not to induce some WIND sound on the guitar sound

maybe this is what I need:

Input clean signal ...  splits into :  clean , Wah, Phase or some other pedals and with a SENOIDAL LFO control the Mix betweed those signals...  right?

You could do a sample and hold circuit into a glide circuit to get a nice smooth transitioning control voltage. Setting the glide time high and the sample and hold LFO fairly slow, you would get what you are after. If you want random, control the sample and hold with white noise. Can't really get more random than that.
