What is Impedance in Audio? Input and Output …
https://virtuosocentral.com/what-is-impedance-in-audio/
In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance measurements, namely input, and output impedances. More on that later.

Consider a mixer outputting a nominal 0dBm line-up signal from a 600Ω output impedance, connected to a tape recorder input of 600Ω input impedance (see Figure 2). (For the difference between dBm and dBu, see the 'Signal Levels' box.) ... We measure audio signal amplitudes in terms of decibels for convenience, and the reference value is always ...
High and Low Impedance Signals - Support - Whirlwind

A high impedance microphone or guitar will usually output a greater signal (voltage) than a low impedance microphone. This high impedance signal works fine and even has some advantages in a sound system as the mixer or amplifier doesn't need to boost the signal as much.
What Is Speaker Impedance and How Does It Work? - Audiosolace
https://audiosolace.com/speaker-impedance-explained/
The word impedance is based on the output current of an amplifier, which is usually AC and not DC, as the latter is found on batteries instead. The amount of impedance indicated in an audio source such as your home theater main unit or even your MP3 player shows the amount of audio signal it sends as AC.

dependent resistance is called impedance; it’s measured in ohms like resistance, but it’s represented by the letter Z. This is the real Ohm’s law: V = IZ. The trick is in figuring out how to design circuits to filter audio signals based on this principle. This is the basis for crossover design! Mathematical background

A high impedance microphone or guitar will usually output a greater signal (voltage) than a low impedance microphone. This high impedance signal works fine and even has some advantages in a sound system as the mixer or amplifier doesn’t need to boost the signal as much. Therefore, any noise on the line is also not amplified as much and this ...

The first issue here is that the pick-ups found in these instruments produce a relatively high impedance signal, so you need to run them into an input with an extremely high impedance. Unfortunately, not all audio gear provides high-impedance inputs. When you run a high-impedance signal into a low-impedance input, there’s going to be a loss ...
