Group kmm-this is a recording of a passing car. There is a lot of wind noise that creates a low rumble. Recorded with a zoom h4 handheld recorder, high gain.
Recorded the 20th of january, 2020 in las vegas, nv on a tascam dr-05x internal mics. A semi truck without a trailer was passing by as i started the recording.
The sound of a car engine idling i grabbed from an old video i recorded. It didn't perfectly loop so i copied the sound, reversed it, and put it after the original sound (making a ping pong effect).
