I'm looking for a sound effect, which is used in the A-4 for the
altitude alert, as well as the RWR. It's a two-tone deedle deedle
deedle sound, and I think it's been used in the movies ("Flight of the
Intruder" I think)

I have some HUD tapes which have the sound, but it's not clean enough to
rip it... At the moment I'm using the "Altitude Altitude" warning from
Falcon 4 :-)



Any ideas where I could find the sound? Or even a sim which has the
right sound I can .. err.. "borrow"? I've looked through Falcon 4 and
Janes F-15, but haven't found it yet...

The F-15 -1 has timing and frequency info for many (if not all) the alert
noises. Does the manual for the A4 have this info buried somewhere maybe?

If it's good enough to get pretty close to the timing and frequency, you
should be able to cobble it together from scratch pretty easily.

Sadly the A-4 "Kahu" refit is not well documented, and I understand that
some of it is still classified (despite it being 11 years since they
were taken out of service). The documentation for the Kahu, even pilot
manuals are rare, so I doubt I will find it that way <lol>

You know, I should have done an F-16 at least there is plenty of info on
the net about them ;-)

Looks like I'll go down the rip from the HUD tapes route!

I have a complete NAVAIR 01-40VC-1 (A-4E/F) manual.. I'll see if there
is anything about it in it..

Thanks Cris, but mine is a local updated version called a "Kahu", which
shoehorned F-16 systems into the old scooter airframe, and a lot of it
is unique to the Kahu avionics fit. The sound however will be from
something else... it's just identifying the right sound <lol>



I will endeavor to rip the sound from the HUD tape, and post a link to
it.. then everyone can hear what it should look like :-)

GOTIT..
LAWS (Low Altitude Warning System)
2 warning lights and aural-warning tone operated in conjunction with the
APN-141 rada altimeter.
when the needle moves below the preset indexer altitude, the
marker-becon light, the low-limit warning light, and the aural-warning
tone are activated for 2 seconds
->the tone is an alternating 700 - 1700 hz tone monitored through the
pilots headset. at a 2 hz repetition rate.
->A reliability warning singal of the frequency range but with a 8 hz
repetition rate .. The reliablitily warning signal sounds for 2 sec
whenever the APN-141 acquires or loses lock-on.

There are spectrum analysis packages for PCs that use the
sound "card" as the input device. You may be able to get all
the information you need from the tapes, and then synthesize
a clean signal as Gene suggests.

A few Google hits:

WOW!



That's pretty impressive... so now I'm off to do some sound synthesizing
;-)



Thanks so much Cris!

Man, there are some smart guys on this list :)

Some very interesting links! Thanks. I'll rip some samples and analyze
them, then compare to the numbers Cris found.

Thanks Roberto ;-)

Really appreciate your help guys

holy beep, batman!
if you're not reacting hearing this tone, you're unconscious or worse :)

sounds good to me, but I don't know the original tone.

I would definitely put it into my sim.

Thanks!

My Skyhawk Avionics expert thought it was pretty good, and another
Friend (and Skyhawk nutter) compared it to the HUD tapes (which I still
haven't had time to dig out!) and says its pretty much bang on.

HUGE thank you to the simpits gang ;-)

Just for kicks, I made a wav file (1) using those numbers.
Sounds right. Results here:
