Minim Waves SQUARE Description A perfect square wave with a 50% duty cycle. Signature ```Wavetable SQUARE ``` Related Waves Wavetable Waveform Example ```/** * This sketch demonstrates how to create synthesized sound with Minim * using an AudioOutput and an Oscil. An Oscil is a UGen object, * one of many different types included with Minim. By using * the numbers 1 thru 5, you can change the waveform being used * by the Oscil to make sound. These basic waveforms are the * basis of much audio synthesis. * * For many more examples of UGens included with Minim, * have a look in the Synthesis folder of the Minim examples. *
