Impedance Matching of Audio Components
http://hyperphysics.phy-astr.gsu.edu/hbase/Audio/imped.html
Impedance Matching. In the early days of high fidelity music systems, it was crucial to pay attention to the impedance matching of devices since loudspeakers were driven by output transformers and the input power of microphones to preamps was something that had to be optimized. The integrated solid state circuits of modern amplifiers have largely removed that …
Is impedance matching important? : Empirical Audio
https://www.empiricalaudio.com/computer-audio/audio-faqs/should-i-match-impedances
There is no specific impedance matching between power amps, speaker cables and loudspeakers, particularly since loudspeakers represent such complex loads. The most important attributes for loudspeaker connections are: Low driver output impedance (.1-.3 ohms is good) Low speaker cable resistance and inductance
How important is impedance matching in audio applications ...

Impedance matching is not used in modern audio electronics. A mic output might be around 600 Ω, while mic preamp inputs are 1 kΩ or more. A line output will be something like 100 Ω, while a line input is more like 10 kΩ. A loudspeaker amplifier will be less than 0.5 Ω, while loudspeakers are more like 4 Ω.

Audio Level & Impedance Matching Transformers create compatible signals between microphones, line-level devices, laptops, digital 75 ohm and 110 ohm AES/EBU devices. For example, Audio Level Matchers allow you to connect a professional studio microphone to a computer or other "consumer" style recording device.

Impedance matching in audio equipment means that the output impedance from one device must be the same as the input impedance of the device that is connecting to. This ensures a good signal transfer between devices. Think of kids on a playground. When everybody gets along, things run smoothly.

In this way the source 'thinks' it is only driving one destination, and the correct impedance matching is maintained, provided that the 75Ω termination is at the end of the line of connected equipment. This same matched impedance concept is used for S/PDIF digital audio signals (on phono or BNC connectors), and also digital audio word clocks.

It can mean "matching" an output impedance of one value or range, to an input impedance of a completely different value or range (this is also done in telephone circuits with a line-matching transformer). There are times and reasons to match I/O impedances in audio, and other times it is not desired.
