Room tone and ambience recorded in a large warehouse space with 25' ceilings and approximately 1800 square feet. The first half of the clip has audible air rushing through the ducts which ceases halfway through, leaving nothing but the rumble of the condensers. The room is rectangular in size. Stereo mic was placed near a side wall and underneath an A/C duct. There were multiple AC ducts in the room, so listen to all of the clips in the series to find one that has the correct intensity and character. Recorded on ITV Studio A soundstage.
