This is a raw recording of central London from east. The main fireworks were at Greenwich side, they can be heard around 13 minute mark but the location had no direct view of that side.
The background noise is unedited, there is no sound sync issues. The fireworks were mostly far away and it took quite a while for the sound to catch up.
