Explore the LabVIEW environment by creating a VI that generates a signal and displays it on the front panel.
Additive synthesis creates complex sounds by adding together individual sinusoidal signals called partials. A partial's frequency and amplitude are each time-varying functions, so a partial is a more flexible version of the harmonic associated with a Fourier series decomposition of a periodic waveform. In this module you will learn about partials, how to model the timbre of natural instruments, various sources of control information for partials, and how to make a sinusoidal oscillator with an instantaneous frequency that varies with time.
Additive synthesis creates complex sounds by adding together individual sinusoidal signals called "partials." In this module you will learn how to synthesize audio waveforms by designing the frequency and amplitude trajectories of the partials. LabVIEW programming techniques for additive synthesis will also be introduced in two examples.
Amplitude modulation (AM) creates interesting special effects when applied to music and speech signals. The mathematics of the modulation property of the Fourier transform are presented as the basis for understanding the AM effect, and several audio demonstrations illustrate the AM effect when applied to simple signals (sinusoids) and speech signals. The audio demonstration is implemented by a LabVIEW VI using an event structure as the basis for real-time interactive parameter control.

Learn about analog synthesizer modules, the foundation for synthesizers based on analog electronics technology. While analog synthesis has largely been replaced by digital techniques, the concepts associated with analog modular synthesis (oscillators, amplifiers, envelope generators, and patches) still form the basis for many digital synthesis algorithms.

Subtractive synthesis techniques often require a wideband excitation source such as a pulse train to drive a time-varying digital filter. Traditional rectangular pulses have theoretically infinite bandwidth, and therefore always introduce aliasing noise into the input signal. A band-limited pulse (BLP) source is free of aliasing problems, and is more suitable for subtractive synthesis algorithms. The mathematics of the band-limited pulse is presented, and a LabVIEW VI is developed to implement the BLP source. An audio demonstration is included.
