Q. Why are audio transformers good to have?
https://www.soundonsound.com/sound-advice/q-why-are-audio-transformers-good-have
Technical Editor Hugh Robjohns replies: Going back to the early days of professional audio — over 50 years ago now — transformers were used to provide electrical isolation between separate items of equipment, provide balanced interfaces (to help minimise interference), and often to provide signal gain (or loss) to help match levels between different devices. In some power …
Audio Transformers - Learn About Electronics

Audio transformers often perform several functions at once: Where used, they allow the AC audio signal to reach the loudspeaker whilst preventing any DC from the amplifier... They provide an isolated external connection for the …

https://electronics.stackexchange.com/questions/23700/why-are-audio-transformers-required
You need a transformer because oscillators use audio jack's power and they need at least 3 volts to work. (3-12 V) But audio output of any non-amplified sound …

Audio Transformers. Audio transformers can: 1) Step up (increase) or step down (decrease) a signal voltage; 2) Increase or decrease the impedance of a circuit; 3) Convert a circuit from unbalanced to balanced and vice versa; 4) Block DC current in a circuit while allowing AC current to flow; 5) Electrically isolate one audio device from another. While transformers are useful in …
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
The audio transformer works at frequencies between 20 Hz to 20 kHz. So, the operation of an Audio transformer has much wider frequency range. As discussed above, the audio transformer uses Impedance balancing technique. It is very useful for balancing amplifiers and loads (Loudspeaker and other) that use a different input or output impedances for …
