This is how terrorist's make their amateur propaganda, the soundtrack of a video is faked to make it sound like Homs is under massive bombardment.

The first video is the unedited version from one videographer who records the date as March 26th 2012, and states it to be in Homs. The explosion of what may be fuel close to a golden dome in the distance can be taken as a point of reference. Two incoming whistling sounds can be heard in the space of the video over more than one minute.

In the second video, a different videographer records the same view showing the same golden dome and the fuel explosion used as the original time reference. The date is again stated as March 26th 2012, and the location Homs. However, this time a ridiculous series of the original two whistling sounds are dubbed in close succession in an amateur fail. In the space of about a minute about 10 whistles can be counted. The video is then uploaded onto youtube while the other videographer also uploads his own video without the edited sounds exposing the fake.
