Audio Input Devices

Digitized Audio Signals

• Audio (analogue) signals can be converted to digital signals by  analogue to digital converters, processed by a computer and converted back with digital to analog converters. This allows computer manipulation of music (See MIDI, below), speech or any recordable sounds.

• Synthetic audio signals can be created by the computer.

• Musical Instrument Digital Interface  (MIDI) devices allow the input and output to any musical instrument capable of electrical I/O. The music, once digitised in the computer’s memory can be processed by musical software giving incredible opportunities for creativity and innovation.
