Heygate Estate has been empty for two years and is awaiting demolition. Once a home for over 3000 people the area is now empty apart from a few leaseholders who have stayed and are in dispute with the local authority. Not wanting to speak too much about something i don't know, i will stick to my personal reasons for being there. I have visited the site a few times previously and conducted audio reference recordings and soundwalks that have enticed me to revisit with some proper equipment for impulse responses. Heygate is truly unique sonically and this is for a few reasons. The architecture of the place is astounding and vast. The long rows of thickset housing close you in from any line of sight (or ear) acting as acoustic blockades that fend off the higher frequencies of the city. What your left with is the low frequency roar of traffic on the woolworth road and London's busiest roundabout in Elephant & Castle. This low end ambience is beautiful and makes it also very quiet past the spectrum of 500hz or so. For getting reflections from corrugated concrete walls this is perfect and that is what we have achieved with the first positioning of our 2 impulse responses.

For our second positioning we wanted to capture a later reflection. We chose this spot and our speaker position with the intention of getting a stereo panorama of the exterior architecture of four of angle blocks. We positioned the speaker behind the right so microphone and aimed it to reflect the impulse like a snooker shot hitting all four cushions. The result was spectacular and as we were running in 96k it can be stretched into a much longer more melancholic representation of the space.
