Need community's help (sound makers)
-
Hi everyone!
I am looking for someone who could generate (synthesize) or could explain me how to generate (using softwares like Audacity) some of the RWR sounds that we can hear in those videos:
(the small crispy sounds, not the beep tones) (barely audible)…
I am searching for a way to generate a sound/sequence based on RF (Radio frequency), PRF (Pulse Repetition Frequency), and PW (Pulse Width).
Be careful, I’m not talking about sampling the sound from videos, but generating (if it is possible) a various sequences from scratch …
Thank you for your help in advance …

1st, u can record similar sound from movie
2nd, change the frq pitch filter etc in editor.
3rd, u can mix 2 sound sample to get police siren. “bi bo bi bo bi bo……”i dunno the backgnd principle, but i will try every function the editor provide. test them 1 by 1

Best to just sample if you ask me but good luck, will be watching.

In Audacity you can generate a tone that has a particular frequency and repetition rate. However ‘finding’ the right settings for a given tone would be, I think, quite difficult if you don’t know what you’re doing (and, no, sorry, I don’t know what I’m doing).

I did just this for the JA37 Viggen sounds. In audacity.
Stall warning etc etc. but then I had the info about the correct frequency. -
Sound like a frequency generator with a way to pulse (another channel with transistor).
Some are sin waves, some are square waves that do a high freq clip.
hook a >8ohm speaker to a freq gen and see what you get.

This is what I tried. But no joy on how to modulate the whole waveform … I can generate tone, but don’t know how to make variations in the tone itself (hard to explain)

Also tried. But like for audacity, I can not modulate the freq nor create pluses.

This is why I am looking for the help of a specialists.

You need to add tracks and create a frequency tone for each track, well, need and need, that was the way I did when making warning sounds etc that had 3 different frequencies.
Then you adjust the start time for each track/tone.
If you choose the “square” tone you will get a sound close to the video, default is sinus. Then it’s just the trick to find the best frequency to fit the video. -

I am not tlaking about the “New guy” tone nor the Missile Launch tone (beeep beeep beeep beeep beeep beeep beeep)
I am talking about the
of the RWR coming from radar.[> 7. RWR AUDIO
In addition to generating threat symbols for each identified threat, the signal
processor also generates threat audio. Threat audio first alerts the aircrew to the
detection of a threat system. This RWR audio is generally referred to as “new
guy” alert audio. The signal processor can also present constant audio from a
selected threat. The aircrew controls this function through the interface control
unit. The constant audio provided by an RWR system can be either “real” or
synthetic. “Real” audio is normally based on the actual pulse repetition frequency
(PRF) of the threat system radar whether the signal processor has identified it or
not. Synthetic audio is based on the classification of the threat (SAM, Al, etc.)](http://falcon.blu3wolf.com/Docs/Electronic-Warfare-Fundamentals.pdf) -
the real world sound is never a pure single wave, it combine many sub wave, which r random. this make the sound feel “real, live”
some editor just generate wave by frq&, total pure sine, it feel “flat, dead, unreal”,
i dunno what is Audacity, but i don’t think software generated sound is a good idea. u can’t generate those random parts. -

But who knows … this is the reason I’am asking here.
Thanks for answers guys.

I’ve worked in the audio production/recording industry for a good portion of my life, and well versed in subtractive synthesis… I believe I can help with your request as specified.
I have access to pretty much any audio hardware / software… There are much better solutions to use than audacity and I also agree you can’t simply emulate the raw tone and need to synthesize using a couple waveforms and possibly some background noise to make it sound less like it came out of a calculator…I’ll take a look at some of these sources and see what’s possible…
The fact that you have the frequency and relationship between the components would make it easier to get the raw tone down square ( no pun intended )

Oky for your proposal Khronik … will wait for an example.

I dont know if this is the sound you meant but this is how i made it:
-I converted the movieclip sound to mp3 and opened in audacity
-I analysed the frequency of the “chirp sound”
-I then created a chirp with the range 13000hz to 752hz with the audacity chirp generator
-I then drawed the curve with the pencil tool by hand and tried to replicate the original curvechirp is 75ms and silence 1411ms
chirp-silence-shirp-silence

I am talking about the

Its been quite some time since I looked up the RWR in the -34. Does the F-16 provide “real” audio as well as synthetic.

Example … when hard locked :
Or like this one painted and/or locked by the FCR:

Well, I guess one could create the different “chirps” but then it’s up to the RWR code to use them

Both… depending on the PFR. IIRC, above 3000mHz for A-A radar and 500mHz for A-G radar, it switch to a generic synthetic tone :
(generic AA) (generic AG)below, it is the real “radar music” :

Hi Dee-Jay,
My son is into sound design. He came up with this in a few minutes work. Is this what you are looking for?

I do think that some of these sounds can be created with randomly playing some other noises layered with a main noise. For instance, have the beeping noise loop at random intervals, and then splice in some of those crunchy, glitchy noises (which sound remarkably like when you import raw data into Audacity from a non-audio file).
Also hi! I’m PumpyHead’s son.
