Making Sin Waves

SinWave

The simplest thing we need to be able to do in synthesis is to create sin waves:

(10000,300)SinWave

The above achieves this. It will create a 10 second long signal at 300Hz. If we want to listen to the result we can do the following:

(10000,300)SinWave Monitor

The above patch will play the sin wave on the computer's default sound output system.

How it works:

(10000,300)

This creates a bunch with two elements. The first element is the number 10000 and the second is the number 300.

SinWave

This takes a bunch of two numbers as its input and forwards a signal containing the appropriate sin wave moving between -1 and 1. The first number from the bunch is the time in milliseconds and the second is the frequency in Hz.

Monitor

This takes a signal as the input and plays it on the computer's default sound output.
