In audio, a mixing console or audio mixer is an electronic device for combining(also called "mixing"), routing, and changing the level, timbre (tone color) and/or dynamics of many different audio signals, such as microphones being used by singers, mics picking up acoustic instruments such as drums or saxophones, or signals from electric or electronic instruments such as the electric bass or synthesizer. In the 2010s, a mixer is able to control  analog or digital signals, depending on the type of mixer. The modified signals (voltages or digital samples) are summed to produce the combined output signals, which are then broadcast, amplified through a sound reinforcement system or recorded (or some combination of these applications).
