Organized by myself alonside the association [Game Audio Denmark](https://gameaudiodenmark.dk/). The Brønshøj water tower in Copenhagen is a defunct water tower, a 34 meter tall concrete structure with a reverb time of about 16 seconds. Long, diffused and very lovely. As an association we were able to rent the space for 8 hours, giving us and our members the opportunity to record experiments and impulse responses. # Phone video field report <iframe width="1120" height="630" src="https://www.youtube.com/embed/j7HhtclxXAc?si=4Dz8cyH3kHNkdvLv" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> # Cursed by wind We were unfortunately haunted by it being a windy day, which would set some of the old metal ornamentation at the circular windows into motion, causing it to clatter with pretty much every wind gust. The windows were most likely 5-10 meters up, and it being a protected building meant we couldn't alter anything in there - even if I we were able to reach it. This meant we very rarely had the full 16 seconds of reverb without interruptions, which made clean and undisturbed recordings near impossible. Sometimes less important for experimentation, but very frustrating for recording clean impulse responses with the full tail of the reverb and any clean source. # Inside We were 8 people present including myself and we still had a good time even if the recordings might not be as usable as we could hope for. Being in a cold, very reverberant space almost non-stop for about 8 hours can, not surprisingly, feel quite oppressive. Moving only a few meters away from each-other complicates spoken communication and just masks all the words and turns it into a reverberant blur. But at least it sounded fantastic. I would love to go back and record in there... in the summer with no winds. ## We tried to the record -> impulse responses (sweeps and balloon pops) -> various instruments (saxophone, violin, guitar, cymbals and ocarina) -> various objects (innards of a grandfather clock, long spring, cobber sheet and the likes). # Post-work We have started to collect the recordings from those who brought a recording device and microphones. The plan is to sort, trim, edit, process, name and metadata tag it and then offer it as a free library to Game Audio Denmark members. ## Links [Game Audio Denmark](https://gameaudiodenmark.dk/) [Brønshøj water tower](https://kulturogfritidn.kk.dk/huse/broenshoej-vandtaarn) ![[Extended Ears/Media/WaterTower_102026/WaterTower_003.jpg | 1000]] <small>(Katrine Amsler brought a copper sheet)</small>
