Audio Transformers for Impedance Matching
https://islproducts.com/design-note/audio-transformers-for-impedance-matching/
Audio transformers are designed to operate within the audio band of frequencies (20Hz to 20kHz) and as such can have applications in the input stage (microphones), output stage (loudspeakers), inter-stage coupling as well as …

OUTPUT AUDIO TRANSFORMER DESIGN The output transformer in a single-ended tube amplifier is the device which matches the high-output impedance of the tube to the low input impedance of the speaker load (4, 8 or 16 Ohm). To design an output transformer, it is necessary to determine the output power according to the tubess characteristics,
Audio Transformers - Learn About Electronics

Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output transformers.
Audio Transformer - The Amazing World of Electronics
https://elamazing.com/2021/05/14/audio-transformer/
We have seen in this tutorial about audio transformers, that audio transformers are used to match impedances between different audio devices, for example, between an amplifier and speaker as a line driver, or between a microphone and amplifier for impedance matching. Unlike power transformers which operate at low frequencies such as 50 or 60Hz, …

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.
Audio Transformers

The design of an audio transformer operating over a 20 Hz to 20 kHz frequency range is much more difficult because these elements often interact in complex ways. For example, materials and techniques which improve low-frequency performance are often detrimental to high-frequency performance and vice-versa.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
An Audio transformer with Step-up feature will step up the voltage or the current level to drive a load across it. Same happens for the Stepdown transformer too. It converts the voltage from higher to lower with the increased current output. The audio transformer also provides impedance matching specifications. When the output of one circuit or device is …
