A 1khz wave, often used as an effect for a flatline, test pattern, censorship, etc. This one more for effect (such as a movie) than a test tone. This was built with a square waveform for maximum loudness.
This sound was recorded when dragging a chair in the gutenberg square at poble nou campus, pompeu fabra university. It was recorded using a zoom h2 with medium gain and directionality of 90 degrees.
This is a sound made in audacity with a high frequency square wave slowed down. I have a question about this effect that sounds like a robot saying ''uaiuai'' ¿which is the name of this effect?if someone knows the name, please comment.
