What is the strength of an audio signal called?

This level of an audio signal is referred to as mic level. Mic level is generally agreed to be between 1 millivolt (−60 dBV) and 100 millivolts (−20 dBV). These are nominal values. Of course, the actual output voltage of a microphone depends highly on the mic sensitivity and the loudness/proximity of the sound source.

What are the 2 types of audio signal?

An audio signal is a representation of sound, typically using either a changing level of electrical voltage for analog signals, or a series of binary numbers for digital signals.

How many types of audio signals are there?

In fact, there are four different types of signals in audio that can cause problems when mismatched. Microphone level, according to a white paper from Azden, is the voltage signal produced by the weakest of all the audio signals. This is because of the nature of how microphones work.
