Hi I'm looking for a sound the "radar" of a submarine makes > kind of a recurring Pinnnnggggggggggg with a quite long release time.
Like the beginning of the song "Das Boot" from U96 (German Tekkno Band)
Anybody an idea?

Regards Walter

There is also this one I uploaded recently ...

Old WWII anti submarine sonar was just a short duration sine wave at around 14Khz. Very high pitch, so it was difficult to hear. The sonar you hear in the movies is a sound effect, and not similar to what was actually in use at the time.

Don't know if this helps you or not.

I think he was looking for the movie sound effect, which is along the lines of the two linked to. An actual sonar sample from a WWII sub would presumably be much harder to come by than some guy twisting knobs on his synth

I found an actual sonar ping sound recording, and uploaded it. I don't think it's posted yet, but the file name is Sonar_Pings.ogg.. I haven't uploaded anything before, and I'm confused because according to my profile I haven't uploaded it yet - but I did - so . . . um . . . ????. Hopefully it's just waiting to be posted.

This should be what you are looking for. This is an authentic sonar ping, at 625Hz. This is NOT the type of sonar a submarine would ever use (those are very high frequency active sonar devices, beyond our hearing range i.e. 100Khz and up) but this IS the type of sound I think you imagine when you say 'submarine'.

Hope this helps

peter, it was in moderation!
I passed it right now.

where did you find this sample? did you record it yourself? did you get it from a place with compatible license?

Oh, thanks Bram. Sorry, I wasn't aware of how things worked here. First post you know.

This sample has been 'around' for quite some time in the sonar community. My 'day job'is designing sonar systems, and producing records when I'm not doing that. I really am not 100% sure of exactly where it came from, but it has been passed back and forth many times among 'sonar people'. We like it because it sounds 'cool', and we generally can't hear most sonar signals due to the very high operating frequency most have. I'm quite positve there are no restrictions since it has been in the public domain for a long time. That's all I know. I know it's also posted at Wikipedia. No clue where it initially came from though.

Thanks Bram
Peter

the sample > owkay ...

wow, strange job!
you wouldn't happen to have some nice recorded-under-water-with-hydrophone sounds to share with us, would you?
