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).
The PCM sampling method is used in many mobile phones and sound cards for personal computers.
There are multiple types of sound chips, which are divided based on their use.
Sound chips come in different forms and use a variety of techniques to generate audio signals.
Sound chips are commonly used in various digital electronic devices, particularly personal computers (including sound cards and motherboards), video game systems (including arcade system boards and video game consoles), electronic musical instruments (including synthesizers, digital synthesizers and electronic keyboards), and digital telecommunications (including digital telephony, digital television, mobile phones and smartphones).
