I have been working on some videos from our recent Excellent Adventure. I use iMovie, which is quite good once you get the hang of it. It has a good library of sounds, including music, but they really do not fit my style.
At the same time, I have been hunting for a good audio source to accompany my drumming. I can produce drone-like sounds typical of the Didgeridoo on my electronic drums. I like that it provides a backdrop without forcing me into a set rhythm or tempo.
Finally, I have been sleeping with white noise for many years now. I found that playing the background noise in the house adds a very pleasant yet non-intrusive touch.
Along comes myNoise. It was developed by a Dutch guy who is really crazy about sounds. Travels all over the world, recording and collaborating with other like-minded people. The result is like the answer to my dreams.
There is a catalog of hundreds of different titles. Each title can be manipulated to add, remove, or change the level of different components of the sound with slider controls. The slider controls can be animated to change levels over time cyclically. Pitch can be accurately controlled. You can play multiple titles together to create combined sounds. It is truly a remarkable piece of programming.
