Audio modules are a type of electronics used in musical applications. They generally consist of an integrated circuit (chip) with various components and associated components (input/output, power supply, and so on). The audio module can be used to create sound effects, synthesizers, enhancers and amplifiers, drum machines, mixers and signal processors. In addition to these types of audio modules, there are many other types of electronics used in sound technology, such as sequencers, signal processors, digital signal processors, and so on. Audio modules are available in various frequencies, signal to noise ratio, distortion, size and power requirements.
