If I hear the HBO ident I think Game of Thrones. I like it. It is soothing. I wanted my own – I purposely left it a little rough around the edges.

The proper one

My take on it

The files and Premiere Pro project are here:

• The TV noise clip is from this tutorial for the switch-on animation. My repo does not contain this video file (TV_SNOW_AN.mp4), you’ll have to download.
• All sounds sourced off freesounds.org, I modified though in Audacity. Original files in repo.
