An audio output transformer connects the output terminals to the internals of the device while providing isolation and/or impedance matching. It operates at audio frequency carrying the audio signal to its destination. It could be loudspeaker drive, or a lower level signal going towards a mixer or amplifier that depends on the context.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
Audio Transformer creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. The primary and secondary winding turns ratio fixed to 1:1. Due to this, the transformer does not alter the voltage or current level.
Valve Amps: Output transformers - Lenard Audio
https://education.lenardaudio.com/en/14_valve_amps_5.html
The output transformer is the heart of a valve amplifier. The right pic shows a stereo Leak amplifier. The two output trannys are rotated 90deg to the power mains tranny to avoid picking up induced hum from the mains tranny external magnetic field. Output trannys contribute most of the distortion in a valve amp and have a limited bandwidth.

1 Audio Transformer Basics Since the birth of audio electronics, the audio transformer has played an important role. When compared to modern miniaturized electronics, a transformer seems large, heavy, and expensive but it continues to …
Output Transformer Impedance
https://www.radioremembered.org/outimp.htm
The function of the audio output transformer is to transform the high impedance of the output tube to match the much lower impedance of the speaker. This is necessary to get an efficient transfer of the audio signal to the speaker. The output transformer as an impedance matching device, works on the principal of reflected load.

Understanding Your Output Transformer Part One by Mark Baier. In today’s world, the role of an amplifier’s output transformer (OT) is well known. As guitarists discover this critical link between your power tubes and the speakers, the important effect it has on your amplifier’s character becomes obvious. In response, an entire cottage industry has arisen to provide tweak happy …

https://forum.allaboutcircuits.com/threads/how-to-test-an-audio-transformer.168870/
Output transformers were used 64 years ago because they were needed to match the high output impedance of vacuum tubes to the low impedance of a speaker. To produce power, a vacuum tube used a wasteful heater and a very high voltage with a low current.
