How does programmable sound generator work?
A programmable sound generator, or PSG, is a sound chip that generates sound waves by synthesizing multiple basic waveforms, and often some kind of noise generator (all controlled by writing data to dedicated registers in the sound chip, hence the name) and combining and mixing these waveforms into a complex waveform.
What is a sound generator called?
A sound generator is a vibrating object which produces a sound. The first kind is simple and is called the vibrating or oscillating piston. Examples of this type of sound generator include the soundboard of a piano, the surfaces of drums and cymbals, the diaphragm of loudspeakers, etc.
What does sound generator do?
As a sound generator operates, it creates a wave of energy that causes a disruption in the air. A sound generator is an object that makes sounds. These sounds may be produced in a nearly infinite number of ways, ranging from a foot stomping on the floor to a fire engine siren.
What’s the bit depth of a PSG chip?

How does NES sound work?
The NES palette is based on NTSC rather than RGB values. The stock NES supports a total of five sound channels, two of which are pulse channels with 4 pulse width settings, one is a triangle wave generator, another is a noise generator (often used for percussion), and the fifth one plays low-quality digital samples.
What is the main idea of sound waves?
The disturbances that travel in a sound wave are vibrations. A is a rapid, back-and-forth motion. Because the medium vibrates back and forth in the same direction as the wave travels, sound is a longitudinal wave. Like all mechanical waves, sound waves transfer energy through a medium.
How do Soundchips work?
A sound chip is an integrated circuit (chip) designed to produce audio signals through digital, analog or mixed-mode electronics. Sound chips are typically fabricated on metal–oxide–semiconductor (MOS) mixed-signal chips that process audio signals (analog and digital signals, for both analog and digital data).
What is FM music production?
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. Digital FM synthesis (implemented as phase modulation) was the basis of several musical instruments beginning as early as 1974.
How many channels does a NES have?
The stock NES supports a total of five sound channels, two of which are pulse channels with 4 pulse width settings, one is a triangle wave generator, another is a noise generator (often used for percussion), and the fifth one plays low-quality digital samples.
