Analog microphones output analog signals (measured in millivolts and commonly outputted through XLR or TRS connections).The differentiating factor, then, of analog and digital microphones is the output: For more information on microphone audio signals, check out my article What Are Microphone Audio Signals, Electrically Speaking? In this regard, all microphones are technically analog first. So microphones create an analog audio signal first. The back-and-forth movement of this diaphragm then causes the creation of an AC voltage, often through electrostatic or electromagnetic principles. Microphones are transducers that convert mechanical wave energy (sound waves) into electrical energy ( analog audio signals or AC voltage).Īll microphones (excluding some marginal caveats) employ a vibrating diaphragm that moves in sympathy with the sound waves around it. These analog signals can then be converted to digital signals if need be. Microphones first produce analog audio signals (AC voltages).

This is the proper way of thinking about whether microphones are analog or digital. Microphones Are Analog First And Digital Second (If At All) Let's talk a bit more about microphones and their roles in digital and analog audio. In fact, the vast majority of microphones today are analog, and the vast majority of modern audio recording is digital.

Just because a microphone is analog or digital does not mean it can only record analog or digital. However, some microphones (like USB mics) are designed with built-in analog-to-digital converters and output digital audio, making them “digital microphones.” Hence, it makes sense that there is a bit of confusion about whether microphones are analog or digital devices or both.Īre microphones analog or digital? Microphones convert sound waves into AC electrical audio signals and are therefore analog devices. Microphones are used every single day to record both analog and digital audio.
