I am trying to use a laptop computer, microphone and probably a preamp to record all sounds present in a police cruiser. I am going to use these recording to supply background noise while testing a speech recognition system for the New Hampshire State Police. I need to be able to pickup everything (i.e. engine noise, sirens, voice, wind...). I have read several of you techincal support documents on connecting professional microphones to a soundcard, so I have fairly good understanding about impedence and signal strength. Could you please recommend an appropriate omni-directional microphone and preamplifier for this situation.
Consider the Shure SM63 microphone, used in conjunction with a battery powered mic preamp such as manufactured by Sound Devices.
