Karaoke, a widely enjoyed form of entertainment, allows singers to perform along with their favorite recorded tracks. Originating in Japan, the word ‘Karaoke’ translates to ’empty orchestra’ or ‘virtual orchestra.’ Today, karaoke machines are prevalent as playback devices in various settings, including films, computers, and mobile phones.
A karaoke machine integrates a karaoke player, amplifier, speakers, and often a TV monitor. The core component, the karaoke player, typically a CD or DVD player, offers graphic output capabilities. This player connects to other karaoke equipment, like TV monitors and sound systems, to function correctly. Karaoke players are generally available in two styles: portable and component.
Portable karaoke players are all-in-one systems, known for their ease of use. These systems are popular for home parties and small entertainment venues, usually consisting of a CD player, microphone, pitch and echo controller, and external speakers with built-in amplifiers.
Component karaoke systems resemble portable systems in size and function but include additional features. These systems are often multi-disc players with multiple microphone inputs, each with separate volume controls. Unlike portable systems, component karaoke systems typically lack built-in speakers or amplifiers, requiring connection to external home or professional sound systems.
The technology behind karaoke machines centers on audio input, audio output, and audio mixing. Regular songs can be input into the machine, with the original singer’s voice suppressed. Some karaoke machines use CD+G discs, a special type of compact disc with graphics capabilities. CD+G players display lyrics and pictures on-screen alongside the music. Karaoke machines can electronically alter the music’s pitch, enabling amateur singers to perform along with music sources most appropriate for their vocal ranges.
