DCO audio, also known as digitally controlled oscillator audio, refers to the sound produced by a type of electronic oscillator that is controlled by digital signals. This technology allows for precise and accurate control over the frequency and amplitude of the audio signal, resulting in high-quality and stable sound output. DCO audio is commonly used in synthesizers, music production equipment, and other electronic devices to create a wide range of sounds and effects. With its advanced digital control capabilities, DCO audio has become an essential tool for musicians and sound engineers in creating unique and dynamic audio compositions.
