[REL] BillCar's Active Sonar Ping Mod Mk.II

[divingbluefrog]

Hi,
Actually there are two "ping" sound in the /sound directory : Echolot_ping.wav and Sonar.wav. They are very similar, the second more high-pitched.
They could be the two different sounds you're looking after. I can't do self-testing at this time, but I hope this can help.

Unless I'm mistaken, the Echolot file is just for the U-boat's depth-sounding.

Think I just found something great!

This is a recording, taken inside a submarine, of active sonar striking it. This is from a recording that was declassified by the USN in the 1950s and released by a sonar development company in 1960, and so would perhaps date from the 1940s.

What we hear is the squeak and, a second later, a sound pretty close to the one I made for this mod: a short, metallic impact sound.

The squeak can be heard throughout the recording, and the metallic impact is audible twice: listen for the ping 3 seconds into the recording and the impact at 4 seconds, and then again with the ping at 13 seconds and the impact at about 15 seconds.

This is not recorded over hydrophones, it sounds like it is recorded on an open microphone inside the submarine.

This will be the basis for the new sound I make. I will take the old recording, lower it slightly, and preface it with the squeak.

This is the second version, based on the link in the post above.

The squeak is close, but the impact sounds different from the one from hnsa.

[BillCar]

There's a good reason for that, actually – the recording quality on the HNSA is rather poor, and so I figured that leaving more echo on impact would make it sound more lively.

If people want, I can make one that is more of a dead-sounding "thunk" like you hear on the recording. However, I am pretty sure that that is just the sound as heard through their low-quality microphone, cutting off the actual fullness of the sound.

I will try and make a dead-sounding mod for later tonight, and will put both links in the OP.

This? Would be awesome.

Try version IIB, I just uploaded it and it mimics the sound on the recording very closely (they have an almost identical sonic profile in the sound editing program I use).

Also remember to use the sounds in game and not just test them as wav files on their own, as they are calibrated to be heard with background noise as well (the sound will be more subtle in the game than if you just listen to the sound file with no background noise).

its really coming along billcar, this last version sounds very cool. the big question: what did it really sound like? heres some stuff i found you might like:
