I mounted the mic inside and on top of the car and drove trough the city, recording some ambulance, traffic, and a scooter that was tooting, later i turned of engine, opened and closed the car door and startet the engine, maybe you find it useful, let me know :). I used the equipment described in my profile.
Two tone siren that is used by all emergency service vehicles, including police, ambulance and fire department (in 2012) in the netherlands. This is not a recording of an actual siren, but generated by a synthesizer at the exact two frequencies that the siren consists of. For a realistic result it is suggested that you mix this with other background sounds and add your own doppler, echo, panning and other effects to suit your needs.
Brussels city street, in the morning. Bus, tram, cars, klaxon, ambulance siren, motocycle. Recorded on 2018/09/27 at 11h15 with a rode nt4, sound devices 302 and an olympus ls100.
Street scene with cars, people talking and ambulance siren in background. Recorded from 4th floor window during mid-day. Recorded with sennheisser mke 600 shotgun mic into an zoom h5.
I did not record this ambience sound! wtfi've left my zoom h1 recorder at a friends place for quite some while until i picked it up today. Accompanied by a few tracks that make sense to us i also found this record, which none of us (not me nor my friend) recognizes as their record. There were two files (which i recognize as takes), so it must be a part of a fictional flick. I've pulled them together here. Here's what i belief it is:ambience of a crime scene with cars approaching, motors running, people alighting and then talking. Seems like the police or other authorities just discovered a corpse.
A randomly generated sound effect that sounds like a silly emergency siren. There is some fuzz in the track. Thanks for listening, and be sure to check out some of my other sound effects!.
