Mobile recording question

[Evil Taper]

you can usually find scenes from best motoring on the bit torrent sites.  i got all of mine through netflix...volumes 1-18 or something of that nature.  What's your budget defined at?

[Netspeed]

If I can keep the entire rig at around $500, that would be good.

I'm not gonna pretend I read this whole thread or even got a full grasp of what your trying to make happen. But I immediatly thought of this new mic:

Made by HHB it has an omni directional condensor capsule and records 1GB of data self contained and small. I do not know about SPL's of what your looking to record, nor what this can handle.

Everyone have a very Merry Christmas (or Holiday depending on your political-correctness).
Thanks for all the great audio recommendations. I still haven't decided yet. Microtrack, JB3, D8, or Hi-MD. Hopefull I can narrow it down soon.

I am still a little confused as to whether you are looking for a entire rig: mics>pre>A/D>recorder, or just a recorder. 

Some other things to keep in mind: 

If you will need to jam the wind @ 40mph-160mph...good luck. 

Also, what about SPL levels?  I am under the impression you are talking 120dB and higher, easy.

You will need to shockmount even the smallest mics again the vibrations...

Just my $.02, but maybe try a rental house (with the insurance option checked) and toy with a couple inexpensive set ups first.  OR try The Geetar Center and their cheapo Oktava omnis with a MD or something...

I am talking entire rig but the main focus right now is storage. Yes, the decibel levels will be high. Do you have a good recommendation for small mics?

Not w/o having an idea of the SP.  The Oktava MK-012 (omni) only goes up to 130dB in 250-8000Hz range which is where most of your sound is going to be.  To get up into the higher SPL's you are talking about more money.

Also, you really only need one mic for a mono signal, correct? 

maybe a AT product would meet what you need.  AT3031 is a cardiod pattern, but has high SPL

The at3032 is a omni and handles similar high SPL's
http://www.audio-technica.com/cms/wired_mics/de35250f2f1be27e/index.html

MSRP on these is only $259 which means they probably retail for around $170ish.

These were both found by cruising the AT web site and searching for 'high spl"

Try it with other sites.  AKG, Sennheiser, Oktava, etc...

Good luck and happy holidaze.

PS, Go by an inexpensive sound meter at Rat Shack and to get a accurate idea of the continual SPL's you will be dealing with.

The ultimate end of all the sounds are going to be ringtones so I guess mono will work. I like the idea of running a sound meter at first to see what the level is at. Is there any compact way to electronically make the mics work if the SPL is too high?

[Netspeed]

What type of mic is used in this setup?

They record video and audio to a Sony miniDV recorder.
