The Sounds of Sins and Squares

On pages 178/179 of The Fiendish Angletron you see what a square wave and a sin wave look like, but if you want to HEAR them move your mouse over the diagrams.

The "MIXTURE"... you'll notice that it seems to sound very quiet to start with, but then seems to get louder. This is because the first bit is a sin wave which only has one very basic harmonic i.e. it only has one low pitched tone. However when the square wave starts taking over, this adds a lot of higher harmonics which give the "buzz" and "wow" effects and make it seem louder. At the very end the higher harmonics are filtered out again to finish on a low sin wave which you'll hardly hear. However if you plug your computer through MASSIVE speakers, the low sin wave will wobble your house to bits.

Note: the Murderous Maths Organisation takes no responsibility for houses that are wobbled to bits by these noises.

If the sounds don't work, then try these links which will probably make your computer turn on your media player or Apple Quicktime, or it might jump off the table, and start fiddling with your hi-fi. SIN WAVE             SQUARE WAVE GROOVY MIXTURE OF SIN AND SQUARE

Here are where the sounds came from!
