Like you've never heard them before in slow motion - turn the volume up on this one!One of the most interesting audio recordings I have listened to in a long time.From the author:"Video is often much more interesting when you speed it up or slow itdown, and the same is sometimes true with sound as well. In this case,both the vocal sound and motion of hummingbirds are reduced in speed toabout 10x slower than real-life, causing the vocalizations they make tobecome much more detailed than you normally get to hear. A few clips atthe beginning let us hear "normal" vocalizations of hummingbirds asthey squabble at the feeder for last-minute feeding rights at dusk.The video was recorded in 848x480 resolution at 240fps using a GoPro Hero3+Black edition , then slowed down to about 30fps for playback usingGoPro's Studio software. The audio was slowed down roughly the sameamount, and since no audio "stretch" effect was used, the pitch andplayback are simply lower and slower. The reverb effect is naturallyproduced by the acoustically reflective hard surfaces around the feeder,and are much longer and more more noticeable than in real time."Description and video courtesy of jcmdi.com/
