The implementation of electronic circuit designs to perform conversions of sound/pressure wave signals to electrical signals, or vice versa, is known as audio electronics. Electronic circuits considered to be part of audio electronics may also be designed to perform specific signal processing operations in order to make specific changes to the signal while it is in electrical form. Furthermore, audio signals can be generated synthetically by generating electric signals from electronic devices. Until the development of digital technologies, audio electronics were traditionally designed using analogue electric circuit techniques. Furthermore, due to their compatible digital nature, digital signals can be manipulated by computer software in much the same way that audio electronic devices can. Both analogue and digital design formats are still used today, and which one is used depends largely on the application. Receive Free Audio & Electronics Magazines.
