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.

A critical device that helps in creating this blend is an audio transformer. Works just like any other conventional transformer; audio transformers are designed to work at audio frequencies, i.e. between 20Hz to 20 KHz. Interestingly, the initial need to design to such transformer was to enhance long distancevoice communication.

What is the audio transformer?
https://www.ht-transformer.com/info/audio-transformer-51344509.html
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 maximum power …

In this article, author Pete Millett explores the different types of power transformers, and why you might choose to use each type in audio equipment. The article addresses issues with low-frequency (50–60Hz) line transformers, but many of the same issues apply to audio-frequency transformers as well. Newcomers to the fine art of audio equipment …

This type of transformer has a laminated core and is usually smaller than power transformers. Transformers operate over the 20 Hz to 20 kHz audio frequency. They are usually used for impedance machines and for voltage amplification. Such transformers are usually designated according to their application as input and output transformers.
Transformers For Small Signal Audio - sound-au.com

Using a NIC to drive the transformer means that the primary inductance doesn't cause low frequency rolloff, so at low levels the output from transformer #1 can be flat down to as low as 8Hz. At realistic levels (around 0.5V RMS) the minimum useable frequency is 20Hz.
