Set the frequency of the phasor~ toġ by typing into the number box connected to its inlet. In the upper-right of the tutorial patcher, open the gate~ object byĬhecking the toggle box. Have slightly different shapes than the ideal, even though their generated spectra Rect~ are all anti-aliased (or band-limited) oscillators, and The upshot of this is that tri~, saw~, and The Nyquist frequency of your audio hardware and folding over creating To avoid the higher harmonics of the mathematically accurate waveforms exceeding Their shapes or, more accurately, the algorithms that generate their shapes. These oscillators in a digital system, however, some changes are made to

Namesake, and a square should look, well, square. Viewed, a triangle wave should look like a triangle, a sawtooth should resemble its The waveforms described above are discussed as optimal shapes: when Raising it towards 1 changes the balance of the harmonics in those two When listening to the tri~ and rect~ objects, adjust the With the Y axis showing the amplitude of the signal at that corresponding The X axis of the graph corresponds not to time, but to frequency, It provides a different view of our signal: that of a spectrogram (or spectrum plot). The second (lower) user interface object is called a spectroscope~: Adjusting those numbers allows us to get a more or less detailed view of the signal entering the object. Two number box objects attached to the scope~ control how many samples of audio it chunks into small buffers which it draws as line segments in the object. The top one is called the scope~ object, and it functions much like an analog oscilloscope, tracing the incoming signal across the X at a regular speed, with the amplitude of the waveform corresponding to the height ( Y axis) of the line. Listen to the result, and also look at its effect on the visuals at the bottom of theĪt the bottom of the tutorial patcher are two MSP user-interface objects that allow us to plot and view a signal. Number box controlling the cutoff frequency and resonance of the filter.

The controls for the lores~ object, adjusting the dial and Some additional logic in the patcher exposes some other features of these Lores~ object to the dac~ and to a pair of graphical objects at theīottom. Own volume control (a *~ object) that feeds them through a It consists of a kslider objectĬontrolling the frequencies of four different MSP objects: cycle~, Objects that allow you to plot signal data along the way. We'll introduce these oscillators here, briefly looking at a couple of On their own, and they are quite useful for creating richer sounds that can be shapedīy filters. MSP has a number of oscillators that create more complex sounds Most of the synthesis work we've looked at thusįar has involved working with sinusoidal oscillators (the cycle~) object,Ĭreating complex spectra through different types of modulation synthesis (e.g. Now that we are familiar with some basic types of filters, we can think aboutĭifferent sounds to use with them.
