The other day, I read an article about a man who had recorded the sounds of crickets chirping, and had then slowed it down to a point where it sounded like human choral voices. Intrigued, I followed a link to the recorded sounds. It was somewhat eerie, but then I noticed another link to someone who had debunked the first guy's work and claimed it was all an elaborate hoax. He then went on to play back the normal sounds of crickets, and progressively recorded them at slower and slower speeds. However, following the links somewhere along the line caused the installation of Soundcloud, which I had never heard of and wasn't aware of its existence until today. Once Soundcloud had been installed (unbeknownst to me). whenever I started Firefox, the sounds would play back. To say that it was annoying is putting it mildly. I tried deleting Firefox and reinstalling it, but the sounds persisted. More puzzling - when I used Chrome, the sounds were absent. Today, I right clicked while Firefox was running and an explanation of Soundcloud popped up. After some research, I learned that there was an icon that I'd never noticed at the extreme left of the navigation bar when Soundcloud was active. I tried right clicking on the icon and was given the option of closing Sooundcloud. I clicked on close and the sounds went away! Apparently, theere are some good uses for Soundcloud, such as repeated playback of messages or music. However, the unannounced installation of this "feature" was annoying and frustrating, particularly because it did not show up in the extensions or addons to Firefox.
