Sound file

[Sam Hough]

Hello,

Does anybody know of any good tiger 1 sound files? gun firing, engine starting etc?

I've found some options but hard to tell which is best.

Thanks

Sam

In this video are they firing blanks? Very little recoil?

[Adrian Harris]

Given the Flak 36 will chuck a shell 10 miles or so, I would sincerely hope they're firing blanks

Hi Sam,

Are you using the Benedini sound system, either the TBS5 or the Mini ? If you are using the TBS5 then you can't download any sounds but if you are using the Mini then there are sounds on Benedini website from 131 at Bovvy.

Dennis.

I'm working on using a raspberry pi so me and my Dad can play to our heart's content mixing sounds, servos, lights, smoke fans... Not sensible but I'm really enjoying putting it all together.

I've lifted one sound from youtube. I'm not sure of the legality but I'll check that out if we ever do get it all in a tank working.

I've started writing a tank simulator so I can test our software without destoying servos (and the tank is not built yet):

If you press "e" it plays the tank sound I've lifted. A/D for turret. W/S for elevation. Mouse drag to rotate the scene. Impressive bug if you rotate either too much as whole tank explodes. I think it is when rotation goes outside 0 - 359 degs.

Be kind! I normally write big boring business apps for a living so this is a bit of a stretch.

Thanks

I like it, especially the red when the gun fires.

[Sam Hough]

More ignorance sorry. Is this (45s in) a dodgy gear change?

I'm still trying to read up on the transmission/steering.

Thanks

Pity we didn't record our drive at Musselburgh.

The Olvar pre-select gear change was revolutionary for its day. The clutch is hydraulically assisted and is only used for moving off and stopping. All other gear changes are done using the pre-select lever. The driver seeks to maintain 2000 rpm engine speed and pre-selects the appropriate gear. The gearbox then makes the gear change. If the engine revs vary plus or minus of 2000 rpm, the gear change is less smooth. On the vid, sounded as though the revs were a little low.

The vid is mistitled. The sound is not that of the turret rotating but of the engine being held at higher than idling rpm in order to achieve rotation. The traverse drive is hydraulic, taking power from the transmission. Speed of traverse varies between 360 and 60 secs per full rotation depending on engine rpm. The Tank Museum have tested 131 and it can still achieve pretty close to the design spec. The gunner used a foot pedal and hydraulic traverse to lay the gun roughly on the bore - target axis and then achieved fine lay using hand elevation and traverse controls.

Hi Stephen,

Have they repaired the traverse gearbox then on 131 because last I heard somebody had left it in gear and the casing had all cracked and they were having to crank it round by hand.

Dennis.

[Stephen White]

Hi, Dennis. Yes, I'd heard that when I was down at the Museum last week.

720 turns on the hand travers for one complete rotation........ Perhaps they sentenced the guilty party to do ten rotations.

The vid above was probably shot at Tank Fest 2012. I can also recall a similar piece on the Tank Museum's DVD Tiger Files.

Looking forward to catching up at Tiger Day.

Stephen

[Sam Hough]

Excellent. Thank you!

I might try and snip out gear change noises and trigger them when there are sudden changes in the
left/right controls.

Maybe it should lift fake rev noises when the gun rotates to match the speed the motor runs at, although I don't think I could manage to do smooth changes in rev noise.

Need to hunt down machine gun sounds.

Thanks

> Speed of traverse varies between 360 and 60 secs per full rotation depending on engine rpm

Does that mean the gunner was in control of the arc of traverse but the driver was in control of the rate

No wonder the Germans were early adopters of intercom systems

Adrian.

[Stephen White]

Nothing wrong with the reversionary mode, which pre-dated intercoms. Consisted of two equal lengths of string, each tied to an appropriate part of the gunner's anatomy, held by the commander. A sharp tug on either string elicited an immediate and appropriate response. Failsafe too as long as you didn't overdo the pull....
