By the time we got to the water’s edge, we could barely hear each other talk over the sound. When we walked farther down the path, the sound got surrealistically louder, as if someone put speakers next to our ears and turned the volume all the way up.
I had my digital camera with me, which also records short AVI videos, so I couldn’t resist recording the sound. The video itself isn’t very interesting, the first one just being the water, and the second being the wetland grass that the frogs like to live in.
Sounds of Spring Peepers with a bullfrog and birds in the background. (6.0M)
Sounds of Spring Peepers 2 with Canada Geese going crazy in the background. (6.2M)
If anyone knows of an easy way to get just the audio from an AVI file, please let me know.
Neat!
This brings back memories of collecting salamanders during mating season and moving them to a new artificial pond last year… There were tons of peepers that night too.
I don’t know of any utilities that are made specifically for extracting audio from AVIs, but the DirectX SDK comes with this utility called GraphEdit that lets you connect various filters together to do all sorts of weird stuff with movie files. You can run it through a AVI Splitter, which will give you the audio and video as separate outputs, and then send the audio to a FileWriter. The DirectX SDK is like 150MB+, so try finding just the utility first.
