I did not find that the sound is coming from.

Citroen C3 2003 1.4i BVA
If the sound gets louder, then you (or your cameras microphone) is getting closer too. If it gets quieter, you are moving the recording device away from the source. Keep moving closer until the sound is at its loudest then you will be closest to its source.simuzer wrote:What is the source of the sound..
