A siren alarm being tested, recorded inside a building nearby. The original recording (available in the pack) is very noisy : this one has been quickly denoised. Some artifacts remain, so I advise to check the original recording to denoise it yourself if you need something better. Two other recording of the same alarm exists : close and far, as well as noisy muffled. See the pack for more information. Recorded with Zoom F1 and MSH6 Capsule, edited in Reaper, denoised with Waves' Z-noise stereo.
